1. Do you have the extendable thigh support piece on the bottom, front part of the seat? That's the easiest way to tell...

2. Trying to convert non-iDrive to iDrive will be alot of cash for parts, labor (if you're not doing it yourself) and programming. I would've tried to find a car that had it from the factory, it's not worth trying to retrofit it IMO.

3. If you don't care about the sound or (marginal) performance benefits of a full exhaust system, just buy the tips, it will look a whole lot better than stock.
