I took my Land Rover into Performance for a few maintenance related issues (brakes, tires, drivetrain, service, belts, etc..). I ended up getting so much more done to my car. I met Evan when he worked at M Service in Walnut Creek and I've tracked him down over the years because I trust him. I bought my last car (BMW e46) because I knew he could service and fix it.
There is nothing like good customer service. Evan called me almost everyday giving me updates (price and timeframes). I feel if you need anything related to an Audi, BMW, Mercedes, Land Rover or Range Rover you should call Performance Autowerk, Evan does clean honest work.
It is super close to Dublin side of the Stoneridge BART station.
