Read all 6 reviews on Google“Dimitri did a phenomenal job on repairing my 2021 BMW M3 he did a massive overall haul of the vehicle and repaired everything to a T. Very grateful for the phenomenal customer service and excellent quality work. Amazing BMW certified repair shop in rock county wisconsin”
“Before finding Beloit Motor Werks, I struggled to find a local, trustworthy mechanic for my European cars. Now I won’t take my cars anywhere else to have work done. Dimitri did a full engine overhaul and reseal on my 2010 BMW 335i along with numerous modifications. He was very professional, gave me understandable technical explanations, and didn’t cut any corners getting my car to my power goal. Overall great experience and very fair pricing.”
“My car was having coolant leak issues, he had informed me it was one of the main coolant flanges and had fixed it.”
“European car oasis. Dimitri skips the fluff and focus entirely on top-tier mechanic work and fair pricing. Highly recommended for honest, expert service for any high end vehicles.”
