I'm absolutely disgusted and disappointed as I'm writing these lines. This repair shop was my place to go for the past 5+ years. I had more than 10 services done at their shop. I always trusted them to be thorough and fair. I'm so sorry that this trust had to run out today. They charged me 330 for a car battery (part only - labor and tax were separate) that I later found out is retailed everywhere for 149, without informing me upfront, and tried to fool me with the 3-year warranty, which is already included by the manufacturer. Now I've begun thinking about how many more times they actually ripped me off, and I didn't find out. I'm escalating this matter to the BAR of California. I'll see what happens next. EDIT: I received a phone call from Mike the next day, offering store credit for my next service, as compensation for my dissatisfaction. I appeciated the gesture and accepted it, and hence changed the rating from 1 to 3 stars. Yet, from now on, I will be more vigilant and will ask for an invoice (including cost estimate, parts and the price per each, part numebrs, etc) everytime before conducting any non-routine repair and service.
