Just went on a 914club weekend get together in Arizona. Drove 1100 miles just for the hell of it.
Route 66 if you want to see pictures.
Premium gas from 3.99 in CA to 3.19 in AZ. Go figure. Watched the guys with 4x4's towing 400hp boats going 80+mph and SUV's going 90. RV's towing trailers full of off road vehicles, etc. I pissed away 50 gallons just for a lark, so imagine how they did.
Europe's gas prices don't stop the believers from doing 130+ in their AMG's at 10mpg. At some point it may hurt enough to stop, but not yet, I guess.
