My willingness to stick with my tour is probably a mix of economic sense and the fact that it's a pretty fun car to drive.
I've still got a year left on it, and I don't want another car payment for at least a few years. Plus, I've put around $3,000 into my car in repairs. So my options are few: sell it for the amount left I owe for it (I'd say I'd be safe selling it for what I owe on it--it has 103,000 and will need some scratch/dent repair) and buy a beater (which I might end up pouring money into anyway); trade it in and get a new car payment (not part of the plan!); or just drive it until it disintegrates in the street (while performing necessary mechanical repairs and maintenance, of course).
I think I'm just going to drive it as long as I can. There are worse cars you could be stuck with. My only thing is the car-guy in me always has the itch to drive something else, just for the sake of driving something else.
