Car repair estimate explained: parts, labor and fees in plain English

A part made by or for the carmaker, in the carmaker’s box. Identical to what the car was built with.

Ask: Is the OEM part required here, or is an OE-equivalent part just as good for this repair?

The same part from the company that supplies the carmaker (Bosch, ZF, Lemförder, Denso and others), sold in its own box. Same quality, often easier to get.

Ask: Which brand is it, and is it the same supplier the factory uses?

A part made by a third party to fit the car. Quality ranges from excellent to poor, so the brand matters more than the label.

Ask: Which brand, and does the warranty change if I choose it?

A used part rebuilt to specification with worn components replaced: common for alternators, starters, steering racks and transmissions.

Ask: Who rebuilt it, and how long is the parts warranty?

A part taken from another vehicle. Sometimes the sensible choice for body panels or hard-to-find modules on older cars.

Ask: What mileage did it come from, and is it covered by any warranty?

A refundable deposit on parts like batteries, alternators and calipers. It is credited back when the old part is returned for rebuilding.

Ask: Has the core credit already been applied to this estimate?

Labor is usually quoted from industry repair guides that list a standard time for each job, not the minutes a technician actually spends.

Ask: Which labor guide is this based on, and how many hours is each line?

When two jobs share the same disassembly (for example a water pump done with a timing belt), the shared steps should not be charged twice.

Ask: Has overlapping labor been taken out where jobs share the same steps?

Time spent testing to find the cause of a problem: scanning, measuring, road testing and reading wiring diagrams. A code from a scanner is a starting point, not a diagnosis.

Ask: What exactly was tested, and what did the test show?

Work the shop sends to a specialist, such as machine-shop work, glass or certain programming. It should be listed as its own line.

Ask: Who is doing the sublet work, and is it covered by your warranty?

A small charge for consumables used during the job: cleaners, rags, lubricants, sealants and fasteners. It should be listed openly, not hidden in labor.

Ask: How is the shop supplies line calculated?

Covers legal disposal of used oil, coolant, refrigerant, tires and batteries.

Ask: Which fluids or parts does this disposal line cover?

The charge for diagnostic time when you do not go ahead with the repair. Some shops apply part of it to the repair if you approve.

Ask: Is the diagnostic fee applied to the repair if I go ahead?

Brakes below minimum, leaking brake lines, tires with cords showing, worn steering joints: things that affect stopping or steering.

Ask: Can you show me a photo or measurement of the worn part?

Wear that is not dangerous yet but will be within months: seeping gaskets, cracked belts, pads near the limit.

Ask: Roughly how long can this wait, and what happens if it does?

Items to look at again at the next service. Not a reason to spend money today.

Ask: What should I watch for before the next visit?

Maintenance listed because of the car’s mileage or age (fluids, filters, plugs), taken from the maker’s schedule.

Ask: Is this in my maker’s schedule for my mileage? (Check our maintenance schedule by mileage.)

Your OK to do a specific line of work. You can approve some lines and decline others.

Ask: Can I approve each line separately and see the total before work starts?

Work discovered once the job is opened up, such as a seized bolt or a second leaking part. It needs your approval before it is added.

Ask: Will you call or text me with photos before adding anything?

Taking an assembly apart (engine, transmission, collision damage) to see the real damage before a firm estimate is possible.

Ask: What does the teardown cost, and is it applied to the repair?

A technical service bulletin is the maker’s known-fix guidance for a common problem. A recall is a safety fix done by the dealer at the maker’s expense.

Ask: Is there a TSB or open recall for this problem on my VIN?

Florida’s Motor Vehicle Repair Act gives you the right to a written estimate before work above the statutory threshold, and the shop needs your approval before the bill goes over that estimate by more than the small margin the law allows.

Ask: Can I have this in writing, with each part and labor line listed?

In Florida you can ask, when you authorize the repair, to have the replaced parts returned to you. Warranty parts and parts with a core charge are the usual exceptions.

Ask: Can you keep the old parts so I can see them?

The shop’s guarantee on parts and labor for the work it did. Check how long it lasts, in months and miles, and whether it is honored at more than one location.

Ask: How long is the warranty, and what does it cover?
