Another new Golf on the board - Congrats!
I hear you on the legroom. I'm 6'3", and I don't think I've got the seat even halfway back on its tracks. I'm sure even a seven footer would have plenty of room. Lots of headroom, too, even with the sunroof. And I love the Blue Graphite - saw it on a wagon at the dealer the other day and was drooling over it!
With your dogs, the wagon is definitely the way to go. My 60lb Black Lab fits okay in the back of the Golf, but he doesn't have lots of room. It's fine for quick trips to the dog park, but I can't imagine cramming a pair of Malamutes back there.
Can't wait for the pics!
