Sounds good to me.
Wish I had that kind of money to spend haha. If you're looking for a car that'll consume miles like nobody's business, you should really take a look at some Benzes in the price range, if that interests you of course. I mean, cars above the 70k range are what Mercedes does best, you know.
I was just over at an Audi dealer, and they had an S8 in a special, sort of independent room. Damn, that thing looks niiice. If there's a local Audi dealer within your area I'd highly advise you check one out. The interior (both front and rear) blows the 7's out of the water if you ask me, and it's not like it's damp on power and handling. With the S trim it's also really handsome, and very mature looking. I think it's a perfect family car...maybe even better than the B7 I dare say?
Honestly, I wouldn't know. My knowledge on these two cars is based purely off of magazines, online articles, and dealer talk.
