That doesn't sound too bad...an extended warranty would be nice: that would cover the door locks.

I have a 99 SVT, black, with 71,000 klicks, sunroof, CD, and new KDWs and if I were to sell (which I don't plan to do), I'd be looking for around 16K I think.
Where are you? Is the vendor known to the CEG? Maybe we could let you know whether the car has been well cared for...regardless, ask for maintenance records - and then talk to the place where he/she has had it serviced. That should give you a good idea whether it has a future.
