What should I do before selling my car?

Clean it professionally, gather your service records, find the second key, and fix small visible items like a burnt-out bulb or worn wiper blade. Those four are cheap or free and help, especially in a private sale. Avoid spending on major mechanical repairs, bodywork or new tires, which rarely return their cost.

Does detailing a car before selling it pay off?

For a private sale, yes — it is the cheapest way to make a good first impression: a clean vehicle reads as a cared-for vehicle, while a dirty one raises doubts about everything a buyer cannot see. Selling to us, there is nothing to clean first.

Do aftermarket modifications increase a car's resale value?

Generally no. Wheels, exhausts, suspension, tint and audio upgrades narrow the buyer pool rather than widening it, since few buyers pay for someone else's taste, and aggressive modifications can reduce value by raising questions about how the vehicle was driven. If you still have the original parts, reinstall them and sell the aftermarket items separately.

Should I buy new tires before selling my car?

Usually not, unless the existing tires are unsafe. Reasonable remaining tread is enough, and new tires rarely return their cost in the sale price. In Quebec a usable winter set does carry value to the next owner — but already owning one is different from buying one in order to sell.

What Actually Adds Value Before You Sell Your Car (And What Does Not)

The instinct before selling is to spend money on the car. Usually that instinct is wrong, and the exceptions are cheap. Here is the list in order of return.

Worth doing

1. Clean it properly — if you sell privately

Condition is judged at first glance, and in a private sale a full interior and exterior cleaning is the cheapest way to make a good first impression. It is not about impressing anyone. It is that a clean car reads as a cared-for car, and a dirty one raises questions about everything you cannot see.

If you do nothing else on this list, do this one. Selling to us? There is nothing to clean or fix first — our offer is based on market data and the condition you describe.

2. Gather the service records — free, and worth real money

Costs nothing but an hour of digging through the glovebox and old emails. At any mileage it improves the number, and at high mileage it becomes one of the most important factors after condition. Documentation converts an unknown risk into a known quantity, and buyers pay for that.

3. Find the second key

Replacement keys for modern vehicles are genuinely expensive, and a missing one is a real deduction. It is probably in a drawer. Look before appraisal day.

4. Fix the small, visible, cheap things

A burnt-out bulb, a wiper blade, a warning light with a trivial cause, a missing hubcap. These are individually minor but collectively they shape the impression of a neglected vehicle. The rule: cheap and visible, yes. Expensive and mechanical, no.

5. Put the original parts back on

If you have the factory wheels or stereo in the garage, reinstall them and sell the aftermarket parts separately. Original configuration appeals to more buyers, and you keep the parts you paid for.

Not worth doing

Major mechanical repairs

A repair restores the vehicle toward its undamaged value; it does not add its cost on top. Spending $3,000 on a transmission does not add $3,000 to the price — it removes a deduction, and often a smaller one than the repair cost. Disclose the issue instead and let it be priced.

Aftermarket modifications

Wheels, exhausts, suspension, tint, lighting, audio. These narrow the buyer pool rather than widening it. Almost nobody pays for someone else's taste, and some modifications actively reduce value by raising questions about how the car was driven.

Bodywork on an older vehicle

Paint and panel work is expensive, and on a vehicle whose value is modest it rarely returns its cost. An honest description of the flaw does the job for free.

A safety inspection you were not asked for

If you are selling as-is to a professional buyer, you do not need one. Paying for an inspection in order to sell is money spent solving a problem you do not have.

New tires, in most cases

Unless the existing tires are unsafe or the vehicle cannot be shown without them, new tires generally do not return their cost. Reasonable tread is enough. The exception in Quebec is a usable winter set, which does carry value to the next owner — but buying one to sell is not the same as already having one.

The one-line version

If you sell privately, spend a little on cleaning. Either way, spend time on paperwork. Do not spend anything on mechanical or cosmetic work — disclose it and let it be priced. The gap between the two lists is often larger than the entire negotiation you were worried about.
