5 stars, and I haven't even been here yet... let me explain why. I called to make an appt to bring my 2006 325i in that was leaking transmission fluid only 45k miles on the car but my warranty had expired 2 weeks prior, and the dealer in Pleasanton wouldn't budge on the $800 repair. I spoke with the owner of the shop, and he walked me though the process on how to get BMW to do the repair, at the same dealership that denied me originally! I followed his advice, and surely enough, BMW paid for the entire repair and a loner car. The owner of M Service didn't receive a dime from me! How is THAT for an honest mechanic?!?!Now that my car is out of warranty, and the 'Ultimate Service' is expired too, I won't be going anywhere else next time I need service... which is way too often on this little car!
