BEWARE OF SHELLY IF YOU HAVE A ///M CAR!!!!!I bought my 01 S54 M Roadster from SHELLY, the guy we bought the car from was a family friend and after he left SHELLY ive had nothing but bad service from here. 01 S54 M Roadster from SHELLY, the guy we bought the car from was a family friend and after he left SHELLY ive had nothing but bad service from here. I know more about issues with my car then the people there, recently i took my car in for an oil service, and when i go to pick the car up they had put on about 10-15 miles on her. I look at my gas gauge and well over 1/4 tank of gas is missing. I have reason to believe that a SHELLY BMW tech/driver etc. took my car out for a spin and abused the hell out of it. Wasting a 1/4 of gas in 10-15 miles is possible but only under extreme throttle and keeping it in the higher rpm range. When I complained to SHELLY all i got was "oh were sorry, but the car had to be test driven after the service" I replied "yes, test driven, but not abused to hell." basically i got nothing, they did nothing, but tell me to FUK OFF. I would think they would be more professional then that. I also have several Mercedes and this kind of incident never happened at MB. We have a CLK55 AMG and no apparent problems of MB guys trashing my vehicle. I'm the one who paid $50K for my car, and $1k for my SO3's. certainly I should be the only one allowed to drive her hard. I also assume that the person who had the consideration to trash my car didnt wait for my engine to be at operating temperature before they had raped my baby. We buy cars very often. SHELLY BMW has lost a customer, because I will never go back again. BTW. Just serveral months ago, SAVAGE BMW totaled a customers S54 E46 M3 on a so called test drive. BE AWARE More
