Granted my car is an M5 but it is the most brilliant car I've ever owned. It does so many things so well and looks so good that I doubt I will ever replace it with anything but another e45 M5, touring or an S38B38 European M5. The cars are classically beautiful [as stated by an earlier poster], offer a decent bit of exclusivity, drive purer than the newer cars and no electronic nannies to break or get in the way of a nice drive.
Glad to see so many people into their cars, as I have spent quite a bit on mine but every dollar has been worth it in my opinion.
