Dilemma: My 1988 BMW M5's throttle was revving on it's own! Solve: I called my usual BMW guy, Sokol, at EuroMotor Cars (also an amazing place for OBDII cars and newer). He said that he does not work on this type of car, so he referred me to Gary/Paula at Vanguard Motors. I called on Tuesday, and Paula answered. I told her that I was recommended by Sokol and described my dilemma. She said that Gary would not be in until Thursday and proceeded to set up an appointment for me.Two days later I arrive at the shop 15 minutes earlier. I am sipping my coffee, and the doors open at about 7:58am (shop hours are 8am-5:30pm). I go inside the well kept office and see an array of BMW and Porsche magazines and books that caught my attention (also, some neat model cars, Bimmers of course, displayed randomly around the office.I was greeted nicely by Gary and introduced me to his wife Paula. Both were so very nice and inviting. I explained my dilemma. He listened closely until I finished (which I thought was pretty cool since most auto shops will not even listen to what a customer is saying).We went to go look at the car. Gary looked it over for a few minutes and tried to replicate the problem I was having. He could not. He suggested that he look into it more and give me a call. As I was waiting for a cab, one of his customer asked if I needed a ride? I WAS SO SURPRISED and said sure. He gave me a ride all the way across to the Embarcadero and we talked about BMWs all the way there. Also he mentioned that he has been a customer of Gary's for a long time.As the day went by, approximately 2:45 pm, I decided to call him. He explained to me what was going on. And said that he can explain more with visuals.When I arrived, Gary was as inviting as he was early that morning. He took the time to explain and show the solve that he was going to do to the car. The temporary solve was because of part being sent from Germany, which Gary had sourced out. He showed me things on the car I did not even know about! So to make this long story short, I have to wait for the parts and will be back again.I left the place with a good feeling...:)
