Your rights as a customer
Many states have auto repair laws. The details differ, so check your state attorney general or consumer protection office.
Written estimates
Many states require shops to give a written estimate on request and to get your approval before doing work that goes above it by more than a set amount.
Old parts
In many places you can ask for your replaced parts back when you approve the work. Ask at drop-off, not after.
Itemized invoice
You should receive an invoice that lists the parts, the labor and whether parts were new, used or rebuilt.
Recalls
Safety recall repairs are free at a franchised dealer for that brand. Check your vehicle identification number on the NHTSA recall lookup.
