Whatever you choose, if possible, get a Certified Pre Owned vehicle from BMW with their extended warranty. This will give you coverage against any unforseen problems. I bought a 01' 4.4 CPO, with every option and havn't had to use the warranty yet. I'm with you, I love the look and feel of the sport package. NAV is usefull and fun for me. This is a great web site! Enjoy.
