Starting this just to be able to put some information for everyone...
I am taking my Smart on a 2000 mile 16 hour road trip, starting out on Friday the 4th at 4am, leaving from my house and driving to Brooklyn Park MN. Then turning around and leaving there Sunday the 6th at 4am and driving back... Gps says its 997 miles one-way, figure I'll do some driving when I get there, plus the miles back, whole trip will probably be over 2000. When I return I will post miles, gas stops, fill up info... Should be a true test of mpg on the highway... this trip will put my Smart over 23,000 miles on the odom.
Wish me luck! Hope I dont get a flat, or go crazy after 32 hours in a smart in 3 days.
