Performance Autowerk is my "go to" shop for anything related to my 1996 BMW Z3. They do an excellent job of fixing what needs to be fixed. More importantly, they always identify potential problems and advise me to watch out for specific signs/symptoms that would indicate that those things need fixing. I've been to other auto shops where they point out problems then describe nightmare scenarios of what might happen without giving me any sense of how likely those things are to happen. At Performance Autowerk, there is no high pressure or scare tactic sales pitch to have everything fixed immediately. They give very frank and sound advice without compromising safety or making you feel dumb for not fixing minor things. They're conveniently located next to the West Dublin BART station and have weekday hours that make it easy to drop off my car for service and pick it up after work. I HIGHLY RECOMMEND them.
