I took my 4-wheel drive Porsche here to get it smogged. I ended up going twice because I failed the first time because of a problem with the catalytic converters, which I had to have replaced. Don and his guys were great - they took my car in very fast, worked efficiently to get the car tested and completed (and explained) all the required paperwork. I've been directed to certain shops because I was told that many shops don't know how to handle smogging German cars - nothing could be farther from the truth at Santa Monica Motors! They were complete experts and professionals, and charged me a reduced price for the second test. Don was super friendly, reliable, and a great sense of humor.
