lol!
I regularly drive my BMW Z3 at 90-100 mph in Florida, for hours at a stretch. I could do that all day, and so can the car, no sweat. Around 120 MPH it gets a bit tiring, though.
Gas mileage? Who cares? The gas mileage nannies can suck my, uh, exhaust.
In Florida I'd be fraid of rubber gators much less real ones for high speed fun runs.....not to mention the little gators in court..........LOL !
If ya have a system to beat the DPS speed traps share it if ya will .....
I have a friend that is stuffing a viper engine in a dodge magnum station wagon. He go the body in a semi dented condition cheap and just "bought" the viper engine outright. It is IMHO the current day version of the old Nomad. When he's done I'll post a few pictures.
