What I'd like to know is whether it would be worthwhile to buy a "green car" used, now that they've been around a while. I never buy new, mostly because I can't afford it but also because I drive only about 5-7,000 miles a year. So far the most I've paid for a car is $4,200 (a '98 Honda Civic). I'd like to go green, especially with the price of gas these days, but is there a $5,000 used hybrid out there, and would it last another 5-10 years the way older model traditional Hondas and Toyotas do? My guess is no.
