That's exactly what I did to obtain the car's specifications.From a very helpful post on another thread, if you go to www.bmwvin.com you will be able to input the last 7 characters of tour VIN and receive back an exact listing if what is in your car. Then e-mail it to yourself for reference. I did this for my wife's 335 xi and my 535 GT xi.
No apology necessary.My error. I thought you might have had it done by the dealer.
