I've been lurking for a long time, admiring all the work that has been done by you all over the last years and learning from it. I was checking out specs from various microcars meanwhile, as I wanted to have a good start hypermiling.
I just bought a Smart Forfour 1.1 as a replacement of my Volvo V70 TDI, so you could say I'm halfway there without doing anything
I choose the Smart as it has a pretty good economy to begin with, while still being able to transport a lot of stuff. The first mod will be to take out the backseats, the second a LPG conversion. The latter wont get me more MPG's, but it will cut my fuel costs with more then 60%.
I've got a whole list of mods in the planning, but I don't wanna bore everyone to death with that in my first post. And yes, a Scangauge or something similar will be the first thing after the LPG.
later,
