Had some regular service performed here on my S5. My water pump was failing and they took care of it. Way better pricing than the dealer.

I’m very happy with the work the guys did at Bash. I had a 3” lift installed from Eurowise for my 2004 Porsche Cayenne. They were fast, polite, and when there were issues with the install they had instant solutions. If you’re on the market for lifting your Porsche, this is definitely the place to go.

Performed a PPI for me on a 2005 Carrera S. Checked for bore scoring and inspected the carbon ceramic brakes and bilstein b16 coilovers. Very convenient, fast and professional.
