My wife and I have been customers of Black Forest Automotive for longer than I can remember. John, Jeff and the whole crew have taken great care of our Porsches and BMW’s over the years, and several cars that were NOT Porsches and BMW’s.
They are always polite and go to great lengths to get our cars back on the road. They have helped us find folks to help us with car needs that they don’t do in house, such as paint and upholstery.

They stand behind their work and meet their promised deadlines.

We remain happy customers.

My wife and I were referred to Black Forest by a good friend of ours. Black Forest was described as honest, careful and helpful. They look out for you.

It’s all been true. As I’ve gotten into performance driving they have advised me on what to do to my 911 and what not to do. Their vast experience has kept me from doing things that would be a mistake with our Porsches.

Black Forest has almost become like family to my wife and I, and certainly is to our Porsches!

“I’ve been a loyal Black Forest customer since 2003, when I bought my first Porsche, a 1984 911.

The staff has always been professional and pleasant to deal with. Jeff Beckman is an excellent Service Manager, blessed the dual gifts of knowledge and patience. On the rare occasion that a problem emerged after the repair, Jeff has always made it right.

The pricing is very fair in my opinion. I have never felt overcharged or pressured to perform unnecessary work.

All the mechanics are more than competent, but Mark Kinninger and Steve Grosekemper in particular are situated closer to the guru end of the scale. I have benefited from their expertise many times and wouldn’t hesitate to let any of Black Forest’s mechanics perform work on my pride and joy.

More recently, Black Forest helped me complete a dream project over the course of the past year, which included building a 3.8L RS engine, re-gearing a G50 transmission, upgrading, corner-balancing, and aligning the suspension. My vision was to create the ultimate expression of a street-going, naturally-aspirated, air-cooled 993, and Black Forest was instrumental in bringing this dream into being.

Highly recommended.”
