Well for what it's worth I recently sold a 1991 CRX HF with 156K on the odometer, very clean, bone stock (only CD player was non OEM), with every single receipt for maintnance since day one...sold it for $3900.
New buyer didn't even haggle with my price since he had been searching for CRX's for a while and saw lots of junk ones out there that were modded by teens. So if you find a clean car, it will be more likely be pricey unless they're hurting for cash, they should hold value. This was about 3 months ago when gas prices were even lower than they are now. If(when) gas prices go up, commuter car prices should go up a little but because the economy is affecting people's bottom line don't expect them to go up much.
