My 08 4.8i with 22,000 currently is coming off lease in May 2011. The replacement cost for a new 5.0 with adaptive drive and equipped like mine is now over $72K vs. the $66K that my car stickered for and the $60K they based the lease off of.

So my quandary is this. Seeing that I can't think of another car that I'd rather be driving right now given my lifesty, do I just buy my car off the lease and keep it, or get a refreshed one, but maybe go down to the 3.5 or even the diesel? I've always turned cars in for something else, but I really do like the X5. Has anyone gone from the 4.8 to the new 3.5? My buyout is approx. 40 or 42K

Thoughts are appreciated.
