I love the classic look of the E53. The E70 looks to much like the X3 from behind. Technology wise the E70 is probably a lot better. But IMO the E53 handles a lot better because of the shorter wheel base.

I just returned my leased 2006 4.4i and bought a Lemans Blue 2006 4.8is. The 4.8is should make a nice garage companion for my 2005 M3.

Cheers
