Why Petty
You talk to the person who works on your car.
Petty Auto Repair is a neighborhood shop in Dorchester, owned and run by Jose Luis Baez, so the person you talk to is the person responsible for your car. The work is the work a car actually needs most: diagnostics that find the real cause, engine repair from a small fix to a full rebuild, brakes, and batteries.
You get a straight explanation in English or Spanish, without the runaround. And you are not driving across Boston for it: the shop is right here in 02124.
How it works
How a repair works here
No slogans. These four things happen on every job because Massachusetts requires them of every repair shop, and because it is how we work.
-
Step 1
A written estimate, signed by you, before any work starts
Before we touch the car you get an estimate in writing that says what will be done and what it will cost, and you sign it. Nothing gets added without your OK.

Step 2
Diagnosis and storage charges, told up front
If there is a charge to find the problem, or to keep the car while you decide, you hear about it before you agree to anything, not on the bill.

Step 3
Your replaced parts come back to you, if you ask
Say so when you drop the car off and the parts we take out go in a box for you. You can see what was worn and what was replaced.

Step 4
An itemized bill that matches the estimate
Parts and labor, line by line, so the bill reads like the estimate you signed. If something changed along the way, you already knew about it.

Not sure what the car needs? Start with a diagnostic. We find the cause, not just the symptom, and explain what the car needs before you decide.
