Got a lot of hate from my BMW brethren, but I'm lovin the switch!
I've only owned BMWs since I started driving in 1999, and it was definitely a great experience and a pleasure to drive each and every one of them. I went from a 1990 325i, to a 1992 525i, to a 1998 540i, to a 2001 540i (and a 1997 318ti as a daily driver for about a year).
I traded the wife's 1998 540i for a Nissan Sentra due to the issues it was having (Valley Pan Gasket leaking, coil packs, CEL, etc) a few months ago, and sold the 2001 540i/6 this and replaced it with a 2011 WRX Limited w/ Nav.
I was a little nervous about going from a $60k car to a $30k car, but my only complaints so far are how cheap the turn signal stalk feels compared to the 540.
