After buying my dream car, I wanted to have a "Go to" mechanic. I had narrowed it down to two local businesses. When I called the shop in San Rafel to ask how much a brake fluid flush was for my 4 series BMW, I was told $168. I called Mellow Motors with the same question, Liz said $178 but I then asked if there was a difference if it was an M vehicle? She yelled back to Nick, who responded... No, same price. So, wanting to be fair, I called the shop in SR back and asked if it made a difference if it was a M vehicle? The response.. yes, absolutely, it's $225 and that it took an extra 15 min. I wasn't trying to trick anyone but that folks is how you get a new customer.
