To date of the 2000 miles I have put on my Smart since I have had it 60 miles was the longest one way trip. That changes tonight. Road trip from New York City to Alberta Va. 406 miles each way. Leaving 2am Sunday morning. Its a solo run just me, my music, my thoughts and my little Smart. The little guy is 6 days out of its service check where it received new rear axles. If the New Jersey Turnpike is repaved it should be a blast. I have a half tank now and will fill up as soon as I get into New Jersey as gas is cheaper in New Jersey.
