Chris was a pleasure to work with. He had the tools and ability to R&R my Crankshaft & Camshaft Position Sensors without dropping the screw so he was able to get the job done quickly. It looks like I've found myself a new mechanic to work on my car's engine when it's cool .
A++++ Chris arrived ahead of schedule Sunday morning at 7AM and installed two upstream Bosch oxygen sensors that I had purchased online. He is polite, professional and extremely knowledgeable particularly about Mercedes. I saved at least $500 buying my own parts and using this service. Highly recommended !!!
