Through the power of your wallet and your review. If some company pisses you off, take your money elsewhere and let as many people as you can know about it. Had my local Mercedes dealership (Star Motors)treat me the same way. I was trying to decide between the E55 and the M5. Guess what I'm driving now? Please don't think I just let the salesman put me off. I also checked out their service and parts department. They treated me worse than their sales department. These type of dealerships whether they be Mercedes or BMW do not deserve your money. Do not give it to them. Mark '00 Dinan M5 '01 X5 4.4 Sport Both purchased through Lauderdale Imports
