My Ride: 2005 330Ci
Just how troublesome ARE E46 M3s?

I still have my first E46 which is a 2005 330Ci, I love the car but I'm constantly plagued by the itch to upgrade. I love the idea of an M for all the obvious reasons, but very leery about all the countless negative things and horror stories I've heard over the years.

So I guess my question is this- can I have realistic expectations of obtaining a well maintained M at a price point that is not ridiculous, and have it last me for any reasonable length of time without having to do some sort of major overhaul (read: engine)? Or should I just plan on doing some sort of swap right off the bat like to an M5 V8 or a boosted M54 or something?
