HI, Guess I actually joined this group on Feb.2,2012 but just saying hi now. I've had a 1997 Z3 for years and just recently bought a 2008 750 Li to keep it company. The Z3 has been great. Sure, some expenses, I'd guess maybe on average $1000 a year for things that broke...maybe less. I'm a bit concerned with 750 as far as potential repair costs - at least it is under factory warranty until November :) Other than that, love that smooth, quiet, powerful ride. /Terry
