While visiting friend today, he wants to check out new Z3's. We go I stay back, listen and observe. It amazes me that after this vehicle being out since 96 and a wealth of free info, this board for just one source, surrounding the car that so many BMW sales people have no clue as to their product. They could not answer one of his inquiries.[All simple basicquestions, H.P. wheel sizes,options, etc.]Was not my dealer, but still a BMW operation. They missed a sale on shear ignorance. Frustrated he left, we had lunch and I answered most of his questions. They didn't even have a brochure for him. They did have about 20 Z3's of various color and engine size. I am taking him to my Dealer soon. Plaza Motors Creve Couer Missouri. Here he will find a professional group.
