Sorry to take this thread in a different direction, but I couldn't resist adding my 2-cents to the "rag-top" sidebar. I am part of a generation where a convertible is a car with a retractable cloth top. No offense to technology, but a car with a retractable hard top is a coupe-roadster, not a convertible. That said, in response to "DENNESSY's" question about the 6-Series, let me put it this way, I'm on my third one so far, my first M Car, and I could not come up with a response when my wife recently asked me what my next car would be.
