I just picked up my 08 r-320 with 16,400 miles certified pre-owned (with the warranty to 100k and 3 years) from dealer in Houston this weekend. I drove it 1200 miles home to Madison, WI through some blizzard type conditions through Illinois and there was not a time that I felt like I was sliding or loose on the roads. It handled like I hoped it would and I was cruising past many vehicles in the ditch and side of the road. I was passing all kinds of SUV's, Pickups and other vehicles that I thought would have handled the conditions better than this "crossover" and was amazed at the performance. I would have been able to drive faster had it not been for the Houston based vehicle being full of standard windshield washer fluid which froze up in my lines and forced me to have a crudded up windshield most of the way through the blizzard. Damn you warm weather climates!! I don't know if it's the 4matic or the 5000 plus pound weight of this rig but it drove amazing through these conditions. I am so far very satisfied with going the extra 1200 miles to pick up this vehicle for my wife and 3 kids to travel in for the future. When I have to replace my 97 e420 with 185k miles on it, I will have a tough decision to make on what Benz I will want to drive next. You will see me on here quite a bit as I add some accessories to this rig: Trailer Hitch, roof rack, bluetooth for my wife's phone, Entertainment system for back 2 rows. Oh Yeah, I will have to remove all the windshield wiper fluid and put in the low temperature stuff that won't freeze.
