Before You Hire

Typical turnaround is same day to 3 days for most jobs. Ask:

Can I get a written estimate with parts and labor listed separately before any work starts?
What is your hourly labor rate, and is there a diagnostic fee? Is it credited toward the repair?
Will you call me for approval if the job grows beyond the estimate?
Are your technicians ASE certified in this kind of repair?
Are the parts new OEM, aftermarket or rebuilt?

Tips

Get a second estimate on any repair over a few hundred dollars.
Ask whether a diagnostic fee is credited toward the repair if you go ahead.
Book time with the shop rather than dropping off without notice; good shops are often booked a few days out.

Getting several quotes? Line them up in the quote comparison tool and read what to check on an estimate before you approve work.
