Bavarian, what can I say they have been great. I have been using them since 2004 when I purchased my first BMW Mini Cooper S . I had just started HPDS with The BMW Club in Boston, I met Dan, then John and Andy, these three guys make an awesome team. They would answer all my crazy questions about my car and then some. There knowledge on BMW maintenance and repair was by far top notch. I highly recommend them and now that I have a new M3 they have started my new adventure in this world, so go see these guys their new place in Winchester just outside Boston is also great.
