2007 BMW 5 Series 530xi 4dr Wagon AWD (3.0L 6cyl 6M)
To me, this is a big car - just as long and heavy as our full sized mini-van. Drives very well and easy around town. I live in Europe (US spec) so tons of fun on autobahn. Easy driving at 130mph with (sleeping) wife and two kids. Night vision is a hoot, but we'll see how useful it is. Owners manual is a tome, but worth the read, esp the voice command section. Once set up iDrive is no issue; though my wife has yet to tackle it.
Comfort seats, nav, nice blend of quiet, comfortable ride and road feel.
Color options lacks imagination (just look at Audi/MB). Why does gray represent 50% one's options. A simple red would be welcome in a sports wagon.
