Bought a 01' Z3 Roadster from them this Spring...very happy with the service so far. The reputation of Co's and BMW is what sold me the car; however the salesman that I 'worked' with was fired shortly after I bought my car. It is a long story but to make it short let's just say that he was better suited selling a Dodge to someone who cannot afford it (high pressure - he didn't understand that BMW's sell themselves and the customer should expect that from them -not being pressured into a sale).
Anyway I had a couple of issues with the car that they have taken care of - very friendly and highly recommended.
