I went there for a smog check. I parked the car on the side and gave the keys to the mechanic. 5 mins later, he told me my car wouldn't start and that the timing belt was probably broken!! He estimated the repairs to $900 ($150 to check the belt and another 800 to change it). I felt really shocked and told the mechanic i would think about it as I was not really convinced by his diagnostic... Later in the afternoon, i eventually called AAA and they towed my car to my usual mechanic in Redwood City. He diagnosed the problem almost instantly (malfunctioning ignition coil) and the part was changed for less than $100... I don't think i'll ever go to this shell again for any kind of service on my car. I really feel they tried to rip me off.
