Thinkmoto,
I understand the common sense of buying a used car to get past the depreciation on new cars. I've found that searching for the right used car takes too much time, especially when one tries to find a stick shift version that hasn't been smoked-in. Then, you have to consider whether the car was properly maintained and if it was in a minor accident that went unreported (won't find that via CarFax). I work enough hours such that convenience of buying new at a higher price is worth it as long as relatively cheaper new cars are the target. I try to drive all my cars till they drop so that compensates for the higher purchase price to a certain extent. I'd drive the Contour into the ground if price of gas doesn't get much higher (I think we haven't seen anything yet in gas prices).
Concerning hybrids, you are correct that the difference between getting the most fuel efficient standard gas car vs. a hybrid is not cost effective on fuel savings unless the car is owned for an incredibly long time. This is more of a moral value; why shouldn't I strive for the highest fuel economy if I can do so. Fossil fuel is a fixed quantity resource that is running out. I can't do much about how others abuse the natural resources but I can do what I feel is the best possible within my means (not a tree-hugger, just behaving responsibly).
Honda del Sols are nice little cars but a two-seater is impractical for my needs. A 4-door sedan with fold-down seats or a station wagon is what I need.
