What's wrong with my car? · Estimates
Is my repair quote fair?
Most of the price on an estimate is two things: the parts and the hours. You can check the parts yourself in a few minutes. Here's how, and where to see what they really cost for your car.
1. Split the estimate into parts and labor
Every estimate should list each part with its own price, then the labor, then small items like shop supplies, fluids and disposal fees. If you only see one total for "brake job" or "tune-up", ask for it broken down. A shop that's charging fairly won't mind.
2. Ask for the brand and part number
"Front brake pads" can mean a budget set or a premium set that costs several times more. Ask what brand each part is and whether it's OEM (from the carmaker) or aftermarket. With the part number you can compare the exact same thing, not a guess.
3. Look up what those parts sell for
Shops mark up the parts they supply. Some markup is normal: they buy it, stand behind it, and handle the return if it fails. What hurts is a big markup you can't see. Put the parts into the form above with your VIN and you'll see what the same parts cost from real sellers, in three tiers, so you know where the shop's number sits.
4. Check the hours
Most shops quote labor from a standard time guide for your exact car and job. Ask how many hours they are charging and what the hourly rate is. If two jobs share the same work (pads and rotors on the same axle, a water pump with a timing belt) the hours should overlap, not stack.
5. Ask what's urgent and what can wait
Ask the mechanic to sort the list: what's unsafe now, what's due soon, and what's a nice-to-have. Ask to see the worn part or a photo of it. A good mechanic is happy to show you.
Common questions
How do I know if a car repair quote is fair?
Split it into parts and labor. Ask the shop for the brand and part number of every part, then look up what those parts sell for. Labor is usually quoted from a standard time guide for the job, so ask how many hours they are charging and at what rate. A fair quote is one where both numbers make sense, not always the cheapest one.
Can I buy my own parts and bring them to a mechanic?
Often, yes, but call first. Some shops will install parts you bring, some won't, and many won't warranty the labor on a part they didn't supply. If you buy your own, get the exact part for your VIN and keep the box and receipt in case it has to go back.
What is the difference between OEM and aftermarket parts?
OEM parts come from the carmaker (or the company that supplies them). Aftermarket parts come from other brands; good ones match or beat OEM, budget ones trade lifespan for price. For brakes, sensors and anything safety related, a known brand is worth it.
What are my rights at a repair shop in California?
In California a shop has to give you a written estimate and get your OK before starting work, and it needs your OK again before charging more than the estimate. You can ask for your replaced parts back when you authorize the job. The Bureau of Automotive Repair (bar.ca.gov) handles complaints.
This is general guidance, not advice about your specific repair. If something sounds unsafe, get it looked at before you drive on it.
Know the symptom but not the part?
