Most mobile mechanics charge a flat price per job or an hourly labor rate. Published national rates run about $80 to $170 an hour, and routine driveway jobs like oil changes, batteries, brakes, alternators and starters mostly land between $75 and $600. The part on your car is what swings the bill the most.
Worth Knowing
- Hourly labor rates posted by national mobile services run about $80 to $170
- Simple jobs like an oil change run near $75 to $120. Alternators and starters run $250 and up
- A diagnostic visit usually costs $50 to $130 before any repair
- Small jobs can cost a bit more than a shop. Big jobs often cost less
- In Michigan a repair facility owes you a written, itemized estimate before work starts
We fix a lot of cars in driveways and parking lots around Westland. The first question on almost every call is the same. What is this going to cost me? It is a fair question, and the internet does a bad job answering it. Most pages give you one huge range and no source. This page gives you the typical numbers by job, where each number came from, and why two sources can be hundreds of dollars apart.
One note before the numbers. The prices below are typical public figures, not our prices. Every car is different, and the only number that counts is the written quote for your car.
Typical Mobile Mechanic Prices by Job
AutoNation Mobile Service, one of the big national mobile repair companies, publishes price ranges for common jobs on its 2026 pricing guide. The table below shows them, with what moves each one.
| Job | Typical Mobile Price | What Moves the Price |
|---|---|---|
| Oil change | $75 to $120 | Oil type and how many quarts your engine takes |
| Battery replacement | $100 to $250 | Battery size and type. Some cars hide the battery under a seat or in the trunk |
| Brake pad replacement | $150 to $350 | Pads only or pads and rotors, one axle or both |
| Alternator replacement | $250 to $600 | New or rebuilt part, and how buried it is in the engine bay |
| Starter replacement | $250 to $550 | Location. Some starters sit under the intake and take hours to reach |
| Diagnostic scan | $50 to $120 | A quick code read costs less than real circuit testing |
Source for every range above is the AutoNation Mobile Service guide, accessed October 2026. These are national figures, not quotes.
For hourly work, the same guide puts mobile labor at about $80 to $170 an hour. YourMechanic's support page says its labor rate depends on the city and runs from $99.99 to $169.99 an hour. Those two sources line up well, so that is a fair range to hold in your head.
Why the Numbers Online Disagree So Much
Online price pages have a problem. The sources do not agree, and sometimes a single page does not agree with itself.
Take the alternator. The AutoNation mobile guide lists $250 to $600. But a SoFi guide citing Kelley Blue Book puts the average full replacement at $747 to $842, parts and labor included. That is a gap of hundreds of dollars for the same job.
Neither one is lying. They are measuring different things. Three things explain most of the gap.
- The part. A rebuilt alternator and a new factory part can be far apart in price. The labor is the same.
- The car. A four cylinder sedan with the alternator up front is an easy job. A V6 with the alternator under other parts is not.
- Who is counting. A national average can include dealer prices. A mobile company's range reflects its own pricing.
Even the AutoNation guide quotes its hourly average two ways, $80 to $170 in one spot and $90 to $170 in another. That is not a scandal. It just shows that any range online is a starting point. Treat it like a weather forecast, not a receipt.
Hourly Rate vs Flat Price
Mobile mechanics usually bill one of two ways.
Flat price. Routine jobs with a known labor time get one price. Oil changes, batteries, brakes and most bolt on parts work this way. YourMechanic says it sets its price from an estimated job time and you pay the same price whether the job runs short or long. That protects you if the bolt is rusted on a Michigan winter car and the job takes longer.
Hourly. Problems nobody has found yet get billed by the hour. Electrical faults, odd noises and no starts often start this way, because the mechanic cannot price a repair until testing shows what failed. That is what a mobile diagnostic visit is for.
One point from YourMechanic's own support page. For small services like an oil change, it says the price may run slightly higher than a local shop, because the mechanic still has to make the drive worth it. For bigger jobs, it says you tend to save more. That matches what we see. The drive is never free. It is either a line on the bill or built into the price.
What Michigan Law Says About Your Quote
National price pages skip this part, and it matters if you live in Westland or anywhere in Michigan. Michigan's Motor Vehicle Service and Repair Act, section 257.1332 sets clear rules for a repair facility.
- A written estimate comes first. Before repair work starts, the facility must give you a written estimate that itemizes labor and parts as closely as it can.
- The diagnosis is priced up front. The cost of a diagnosis has to be in the written estimate before the diagnosis is done.
- No surprise overages. The facility cannot charge more than the estimate without your consent, written or spoken, given before the extra work. The one exception is small. If you did not sign a waiver, it can go over by 10% or $50, whichever is less.
- Cheaper means cheaper. If the real cost comes in under the estimate, you pay only the real cost.
- A waiver gives up these rights. If someone hands you a form saying you give up your right to an estimate, read it slowly. The law says it must be in large bold capital letters so you notice it.
One more rule. Under section 257.1334a, a written estimate is not required when the total job is under $50, unless you ask for one. So ask.
Our take is simple. Whoever you call, shop or mobile, get the number in writing before anyone starts. A mechanic who will not put it in writing is telling you something.
Six Questions That Get You a Real Number
You will get a tighter quote if you give the mechanic good information and ask the right questions.
- Give the year, make, model and engine size. A 2.0 and a 3.5 of the same car can be very different jobs.
- Describe what the car does, not what you think broke. "Clicks once and will not crank" helps more than "I think it is the starter."
- Ask if the part is new or rebuilt. This one question explains most price gaps between quotes.
- Ask if the diagnostic fee counts toward the repair. AutoNation notes many mobile mechanics credit it if you go ahead with the fix.
- Ask for the total at your address. Labor, parts, any trip charge and tax, all in one number.
- Ask what is covered after the job. Get the parts and labor coverage in writing.

- Is it cheaper to get a mobile mechanic?
