Benzin Motorworks The Benzin Motor Works team of technicians have years of hands-on experience diagnosing and servicing your specific model of Mercedes-Benz, BMW, Mini Cooper or HUMMER H1 Tulsa Oklahoma!!. My personal experience with taking my Mercedes to Benzin Motorwerks. I would avoid this place at all costs. Make sure you cover the diagnostic charge over and over. Record the conversation or sign an agreement. If you happen to decline the repairs for their very expensive charges, you will have added expense to your diagnostic that was not discussed. Once you begin to inquire about the additional charges that you were not told of, nor approved, one of the owners Denny will come and argue and threaten to hold your car hostage until you pay his fees not approved. This was my experience and I would never recommend this shop to anyone. There is a good Mercedes benz shop on 6th street in Tulsa with Ou2019brian or Jason at Bezworks in Broken Arrow. Unless you want sly, con-like owner to over charge you on approved costsu2026this is your place to go. Denny was extremely rude, extremely agressive, and cursing….acting like an idiot.
