I trained for my drivers license in an E21 320 back in 1983 and I have been hooked ever since. Went astray for some years, driving Saab's and Audi's, but when the E92 model came out in late 2006 I was hooked on the design again.
All it took was one testdrive and I was "back"
Now my wife is totally hooked as well, and she doesn't want anything else than a BMW either. At this point all I need to contemplate is whether to get a 3 series or a 5 series the next time, unless of course I can talk my wife into letting me buy a Z4is when the son moves out of the house in a year or 2
