It’s a cliche writing “I would give 10 stars if I could,” but that’s how I feel about Sisco. I say this with a caveat, however, as Sisco works alone, and if too many people discover this hidden gem of a mechanical genius, I’m afraid he won’t have time for me, when I bring my car back for more work. When my BMW started displaying alarming warnings, as air bag malfunction, I brought it to local repair shops. All they could do was reset the sensor, after being unable to diagnose the cause. After two or three episodes, I asked several local friends for a place that specializes in BMWs. One name consistently came up : Sisco, from Green Mountain Performance. Like a surgeon delicately operating on a patient, he methodically and carefully took my car apart, and discovered mice had been dining on the wiring like linguini, and had urinated over several electrical modules, destroying them. Sisco ordered the parts, rewired what the mice ruined, and my dashboard no longer flashes at me. The price Cisco charged for all the hours he worked was unbelievably inexpensive! Sisco only works on European autos, so if your car is having an issue, forget the dealer. Head to Sisco. You will drive away very happy.

Sisco has saved my old Mini! He resolved th issue with the Service Engine Soon light that other garages had failed to fix for four years. I knew I had a great shot at passing inspection with this place when I left it with the guy with racing Porsches, XKEs, Triumph TR 3's and Mercedes in his care.

Cisco is amazing! With his hands full with 2 restoration projects when I stopped in with my BMW after having received bad advice some other mechanics , I was so lucky to have found him! he dropped what he was doing to come out and take a look at my issue, which at the time was non-functioning windshield wipers. In less than 5 minutes he discovered the problem and a simple fix! He literally saved me hundreds of dollars. I am in the process of rebuilding my valve cover and cooling system but will be bringing it to him as soon as he has availability for things that require a lift/power tools and his vast knowledge without wasting your time. After too many bad experiences with mechanics actually breaking parts, I would not let anyone other than Cisco touch my Bimmer!!

Over the past year I've gone to GMP a number of times for servicing my 1989 Porsche 911. The service has always been knowledgeable and professional. I'm planning on continuing to take my car there in the future and would feel confident in recommending GMP to my friends and other car owners in need of more specialized service.

Being first time owners of a "new to us" used Mercedes GLK350 SUV, it took a lot of research to find just the right place to bring the vehicle when the check engine light fired. Facebook to the rescue! I posted a query on Facebook and got good references for this company. Mercedes dealerships were a long distance away and had very poor reviews..something that matches my past experience with dealership maintenance. Expensive and inexperienced. I emailed Sisco about our vehicle issues, and our concerns in identifying someone that can provide the service we needed at a fair price. He was patient and thorough in his responses- which resulted in our taking our vehicle to him. His shop is spotless. He enrolled the owner is the decision making process, and follows my personal philosophy of "if it's nor broken, don't fix it". He found an odd issue with the car, and was open and responsive when I called back with a possible cause after googling the issue. His service was complete, positive and priced fairly. I believe that had I gone to a dealer, it would have been very costly for the same work. Thank you Sisco, for a job well done. We look forward to developing a long term relationship.
