I'm pretty much not sold on the gas-hybrid avenue as far as out right buying one. I think that they might be better for someone to lease (2-3 years) when taking the battery replacement costs down the road into consideration.
I keep thinking I might go the VW Jetta TDI diesel route as I know a friend with the pre-TDI diesel in a bug that gets like 50+ miles per gallon to work. Plus, I love my Kubota GR2100 diesel AWD tractor...
My only concern here though is the high cost of diesel...especially during the home heating season as it seems like demand is intertwined with home heating oil & therefore both go up alot during the winter months.
I once bought 50 gallons of diesel to heat a house that'd run out of oil in the winter, on the weekend. Pretty much the same stuff.
