Green Mountain Performance Co.

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

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.

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.
