I have to say of all the full size luxury cars, the only ones I liked were the 7 Series and A8. While large, they had a youthful look to them and to me they were still cars you want to drive, not be driven in.
A little off topic here.
I started to like the Merc after a romp on the highway in my hybrid when some girls in an AMG version were trying to "keep up." I say that as they were the type to make a bee line for the left lane and stick there while I worked my way through in the right lane and left them, then they find a way through, then zoom past me only to get stuck again. They seemed surprised that they could never lose me and that a hybrid was rolling with them. Was a "caravan" consisting of the Merc AMG, Camry V6 and a Toaureg. They wouldn't let me in as I guess they figured I couldn't keep up, but after multiple passes, the girls decided to follow my route. Mr Touareg wasn't a much of a follower and he blew past us and past a state trooper in an unmarked car, that had just wrapped up with another stop who came out and nabbed him. The girls pulled up along side and waved while looking the hybrid over, after some more miles I waved them past as I was going to exit. I thought, wow, that car really can move and handle well, which lead to me watching videos on them, then the K9 was announced and I was like, yeah! If Biermann does his magic on that to make it a drivers car, I might just have to go for one.
Of course I was waiting for it to come out before deciding on the Stinger but sadly, it still hasn't materialized. WHen they drop here, I will be going to drive one!
