I'd suggest going on a long cruise and watching the meter to get an idea of the fuel economy, or at least tracking miles/kilos between tank fills would go a long way for a potential buyer. Most buyers want some idea of what they are signing up for fuel economy wise. It's not that low mpgs would deter me personally, I just want to know what I'd be signing up for! And it would be very easy on your part to provide this test. Very cool vehicle... I'm rolling over its potential in my mind. What is the overall height?
