If you want one answer: buy a cup-holder insert first. It is one of the smallest purchases you can make for either car, it fits across generations so you can order it without research, and it fixes the single most annoying cleaning job in the cabin. The rest of this page is the four other small parts worth owning, and then the part most cheap-accessory lists leave out: where cheap is the wrong call.
We do not publish prices on this site, so this page is not ranked by a number. It is ranked by a test: a cheap accessory is worth buying when it fixes something you notice every day, carries almost no fitment risk, and can be removed without leaving a mark. Everything above passes all three. A surprising amount of what gets sold as a cheap Tesla accessory fails at least two.
The three tests a cheap accessory has to pass
- No adhesive. Adhesive is what turns a small purchase into a permanent decision, and the cheaper the part the more likely its adhesive is the only thing holding it in. A part that drops in can be thrown away without consequence.
- Low fitment risk. The parts above are listed across multiple generations, which means ordering the wrong one is hard. That matters more at the cheap end, because the cost of returning a small item often exceeds the item.
- It fixes a daily annoyance, not a hypothetical one. A cup-holder you clean weekly, a shelf your phone slides off every drive, a vent your child posts food into. Those are real. 'Protection' against something that has not happened is where cheap purchases go to be forgotten.
| Part | Generations listed | Adhesive? | What it actually fixes |
|---|---|---|---|
| Cup-holder insert | Model Y 2020-2024 and Juniper, Model 3 2017-2023 and Highland | No | A cavity you cannot clean without a cotton bud |
| Under-screen tray | Model Y 2020-2024 and Juniper, Model 3 2017-2023 and Highland | No | A phone sliding off a flat shelf at every corner |
| Under-seat vent covers | Model Y 2020-2024 and Juniper, Model 3 2017-2023 and Highland | No | Objects falling into the rear vents, which is the usual rattle |
| Screen edge frame | Model Y 2020-2024 and Juniper, Model 3 2017-2023 and Highland | No | Knocks to the screen corner, without covering the display |
| Console tray | Model Y 2020-2024 and Juniper, Model 3 2017-2023 and Highland | No | Loose items rolling around in an open console |
Where buying cheap costs more than buying nothing
Four categories, and they are consistent. The first is floor liners. A cheap flat mat cut to an approximate outline does not follow the footwell, so grit works underneath it and sits against the carpet - the exact damage the mat was bought to prevent, now hidden from view. If the budget does not reach a molded liner, the honest move is to wait rather than to buy a sheet. Are all-weather floor mats worth it sets out that case in full.
The second is screen protectors. This is the one category where the cheap option carries a risk that is not financial: Tesla's owner's manual advises against applying a protector to the touchscreen at all, citing unintended inputs and touch response, and a thin, poorly cut piece of film is the version of this purchase most likely to produce exactly those symptoms. Read the warranty guide before spending anything here, cheap or not.
The third is anything structural that is held on with tape - sill plates, trim strips, phone mounts on the screen bezel. The adhesive is the product. When it fails in summer heat it either falls off or leaves residue on a surface you cannot replace cheaply. The fourth is universal-fit soft goods, particularly seat covers: a cover sized rather than cut to the seat is the one accessory class where a bad fit can interfere with a seat-side airbag, which is not a budget question at all.

Scores are our editorial assessment of fitment scope, published materials and coverage. They are not lab measurements and we have not tested these products.
1. Best first cheap buy
BASENOR cup-holder insert
The cup-holder well is the dirtiest cavity in the car and the one you cannot reach into with a cloth. An insert turns cleaning it from a cotton-bud job into lifting a piece of silicone out at the sink. It is listed across both Model Y and Model 3 generations, so it is close to fitment-proof, and nothing about it is adhesive.
Best for: Stopping cups from rattling and tipping
Fits: Model Y (2020-2024) · Model Y Juniper (2025-2026) · Model 3 (2017-2023) · Model 3 Highland (2024-2026)
What works
- Tesla's cup wells are wide, and a narrow cup rattles in them constantly — this is the direct fix
- Cheapest single accessory on this site that you will notice every day
What does not
- Reduces the maximum cup diameter the well can take
- Needs lifting out to clean properly after a spill
Manufacturer specifications
- Insert mat shaped to the console cup-holder wells
- Soft compound chosen to damp movement
- Supplied as part of the four-piece set and separately
Specifications as published by the manufacturer. We have not independently tested this product.

2. Most used per dollar
BASENOR under-screen console organizer tray
The shelf under the screen is where everyone already puts a phone, a key card and sunglasses, and it is a flat, slippery surface. A tray with a lip stops the sliding. It is listed for all four five-seat generations, which is unusual in this category and the reason it is a safe small purchase.
Best for: The dead space under the touchscreen
Fits: Model Y (2020-2024) · Model Y Juniper (2025-2026) · Model 3 (2017-2023) · Model 3 Highland (2024-2026)
What works
- Turns a shelf that items slide straight off into a usable tray
- No adhesive means no residue when you sell the car
What does not
- A friction fit can shift if you load it heavily and corner hard
- Single-purpose — it does nothing for the armrest bin or cup holders
Manufacturer specifications
- Non-slip base, no adhesive required
- Shaped to the shelf beneath the center display
- Listed across Model Y and Model 3 fitments
Specifications as published by the manufacturer. We have not independently tested this product.
Specification sources: BASENOR under-screen console organizer tray
3. Cheapest fix for a real fault
Under-seat air vent covers
The rear-facing vents under the front seats sit at toy height and swallow raisins, coins and crayons, which is where under-seat rattles come from. Covers are a small, cheap, fully reversible part that prevents the one problem in this car that is genuinely annoying to undo. They restrict airflow slightly, which is the trade.
Best for: Stopping debris falling into the rear footwell vents
Fits: Model Y (2020-2024) · Model Y Juniper (2025-2026) · Model 3 (2017-2023) · Model 3 Highland (2024-2026)
What works
- Those vents collect coins, crumbs and small toys, and clearing them is genuinely awkward
- No adhesive, so nothing is permanent
- One of the cheapest protective parts on the car
What does not
- Any cover restricts airflow to some degree — fit the open-grille type, not a solid panel
- Easy to dislodge when vacuuming
Manufacturer specifications
- Grille covers for the rear-facing vents beneath the front seats
- Clip or friction fit with no adhesive
- Listed across Model 3 and Model Y fitments
Specifications as published by the manufacturer. We have not independently tested this product.

4. Cheap alternative to a screen protector
TOPABYTE screen edge protector frame
If you want the screen's edges protected but you have read Tesla's position on applying film to the touchscreen, an edge frame is the small purchase that does not cover the display at all. It protects the corner that actually gets knocked by a ring or a bag strap, and leaves the glass untouched.
Best for: Owners who want the bezel protected without covering the glass
Fits: Model Y Juniper (2025-2026) · Model 3 Highland (2024-2026) · Model Y (2020-2024) · Model 3 (2017-2023)
What works
- Avoids Tesla's stated concerns entirely, because nothing is applied over the touch layer
- Protects the corner the display is most often knocked against
What does not
- Does nothing about scratches or glare on the glass itself
- Sold as part of a bundle, so you may be buying two pieces you did not want
Manufacturer specifications
- Frame that protects the display surround, not the touch surface
- Part of a three-piece console accessory set
- Listed as compatible with the 2026 Model Y Juniper
Specifications as published by the manufacturer. We have not independently tested this product.

5. Best cheap console fix
Tesery console tray
A single tray rather than a four-piece set, listed across both cars and both generations. On a budget this is the piece to buy: it is the one part of a console organizer kit that changes how you use the car, and the rest of the kit mostly fills space you were not using anyway.
Best for: A single tray without buying a set
Fits: Model Y (2020-2024) · Model Y Juniper (2025-2026) · Model 3 (2017-2023) · Model 3 Highland (2024-2026)
What works
- Buy exactly the one piece you want with no bundle
- Simple shape means fewer edges to fit badly
What does not
- Hard plastic, so it can click against the console on rough surfaces
- Does nothing for the armrest or the cup wells
Manufacturer specifications
- Single molded tray for the console well
- Listed across Model Y and Model 3 fitments
- Drop-in, no adhesive
Specifications as published by the manufacturer. We have not independently tested this product.
Specification sources: Tesery Model 3 / Model Y mud flaps
What to buy in what order on a small budget
Cup-holder insert, then under-screen tray, then console tray. Those three are the ones you will touch every day, and between them they cost a fraction of one molded liner set. If there is a child in the back, move the vent covers to the top of the list - the thing they prevent is the only item here that is awkward and expensive to put right after the fact.
The screen edge frame is the one to think about rather than buy reflexively. It is a sensible purchase if your worry is physical knocks to the display corner; it is the wrong purchase if what you actually want is scratch protection across the whole screen, because it does not cover the screen. Deciding which of those you want is the entire question, and do you need a screen protector is the page for it.
Our call
Cheap accessories are at their best when they are small, removable and aimed at a daily irritation. They are at their worst when they are cheap versions of parts whose whole value is precision - liners, protectors, anything molded. Spend the small money on the five parts above, and when you come to buy a liner, buy the liner properly or wait until you can.
If you are shopping for someone else rather than yourself, the fitment constraint changes the answer, because you may not know their exact car. Tesla gifts under $50 covers the same price band from that angle, with the parts chosen so that the generation does not matter.
Questions people actually ask
What is the cheapest Tesla accessory actually worth buying?
A cup-holder insert. It is among the smallest purchases available for either car, it is listed across both Model Y and Model 3 generations so ordering the wrong one is difficult, and it turns the cup-holder well from something you clean with a cotton bud into something you lift out and rinse.
Why are there no prices on this page?
Because a price we copied down weeks ago is worse than no price - it is a number you might act on that is no longer true. Every buy button on this site goes to Amazon so you can see the current figure. The ranking here is by what the part does, not by what it costs.
Are cheap Tesla floor mats a false economy?
Usually, yes. The value of a liner is in following the footwell exactly, and that is the first thing a cheap flat mat gives up. Grit then works under the mat and sits against the carpet, which is the damage you were trying to avoid, happening where you cannot see it.
Is a cheap screen protector risky?
It carries a risk that is not about money. Tesla advises against fitting a touchscreen protector at all, citing unintended inputs and touch responsiveness, and a thin, imprecisely cut film is the most likely version of this purchase to produce those symptoms. Read our warranty guide before buying one at any price.
