Another question - do you need a car? Long commute to work or live in a car-centric area?
IMHO, purchasing an older car in a private purchase that isn't pristine and comes with tons of records comes with some uncertainty. Buying a Civic, less so if you can tell it hasn't been trashed around.
All things being equal, if you can keep the tC for a long time, and you require reliable, everyday transportation, don't turn a stable situation into a potential problem.
If you don't have a "mission critical" need for a car, then go ahead and reduce your costs to better match your level of dependence.
My wife and I have been thinking about selling our 2010 Fit Sport. A slightly off-mustache vehicle in that it has paddle shifters and a nav system built in (we wanted stability control - the rest was part of the package so I was told), but we get these postcards in the mail from Honda dealers saying they have buyers lined up and want to make an offer.
I would see what the offer is, but the car runs great, and my wife has a long commute, so I wouldn't want to trade down in potential reliability. Also, if used Fits are that hard to find, what am I going to replace it with?
