I'll have to get back to you on that once I start calculating mileage and fuel use.
My friends have said the same thing a few times. I've always got some kind of unusual project going on, and have enough projects to keep me occupied for a long time.
Currently (aside from the Dakota getting some new parts and paint soon), I'm helping a friend convert his '90 Dodge Daytona over to a Supercharged AWD car. And then when I'm not doing that, I'm building a guitar for myself from scratch (A nifty Fretless 7 String)
