I've got a 87 g50 coupe, 210K mi, that I got as a tired car and started fixing up. Fun to drive, but needs a new headliner, nicer carpet, and needs oil every tankful of gas. Been looking at engine rebuild costs and have started thinking of buying up to get a similar car with 100K (or more) less miles that has been attended to.
Does this make sense

? Seems the nicer cars are in the 20 to 22K range and my car is likely in the 11 to13K range. After taxes and other fees (Republik of Kalifornia...) is getting close to a 10K differential. Or not?
I was thinking of a 993, but prices seem to have gone nutty this year.
thanks!
