Since moving to AZ I wanted to find a mechanic that I could trust to do good work, stand behind the work they do, charge fare prices and be honest with me. I read some Yelp reviews for Stamps and thought they might fit the bill. I talked with the owners on a previous visit and they said all the right things. I had them do some fairly minor things before which I thought might be a little pricey but did not break the bank so when I had some brake work to do on my F-150, I went back to Stamps. I should note that in my younger days I did work on cars quite a bit so I'm probably not as easy as some to snooker.
Stamps did a brake inspection on my truck and told me that I basically needed new everything including rotors, calipers, pads, wheel bearings, et al. The tab was an astounding $1,500+. I tried to see if anything was optional to save cost but they said none of the rotors could be turned within tolerance and I needed all new parts for the front brakes. The cost seemed excessive so I decided to get a second opinion before proceeding.
So I went to the new Brakes-Plus shop near Stamps and had them look at my brakes. They concluded that I needed one new rotor (3 of 4 could be saved), new front calipers and that the wheel bearings were fine. THE COST WAS ONE-HALF that quoted by Stamps. I noted that all the parts quoted by Stamps were also about 50% more than BP.
Based on my experience, the bottom line is that Stamps appears to be overpriced and quotes work/parts you may not need. Caveat Emptor (buyer-beware).
