Having seen the route of the actual tour this year, its maybe 35% on the freeway. I'm driving 560 miles on Sunday to get to my folks house in the Nashville Metro (3 nights there and 3 on the road), but as you mention, it doesn't matter for me, I can pretty easily cruise at 80 and 2200 rpm so it's no issue. I think people who are patient could do it pretty easily w/o overdrive. Some people wouldn't mind being inside of a car where its 100 for days, not really for me but its possible.
I have been working on a lot of detail items for the car, butyl taped the holes shut in the firewall, rebuilt the windshield washer system, worked on a fuel economy tune, probably going to implement fuel table switching this weekend. Haven't decided if I'm going to buy a helmet to Autocross or not.
Anyone who's going, I did put the Duster 340 stickers on the car. Got you a nice picture of the flaws on the car too :)
