Hi,
I always wanted to get a Porsche and now is the time that I need a second car as a daily driver. Someone is offering a '90 964 targa C4 with 110k miles on craigslist and I like the car. There is an issue with the transmission (the CO describes it as a clunking sound), but the rest seems to be well maintained (new clutch, rebuild A/C, clean engine, no leaks).
But of course I'll get a PPI, since I am not a Porsche expert (but hopefully will be soon

).
My question is how much should I set aside for a transmission repair? I know the range will be quite large, but I just would like to get a feeling for the range?
If I do it myself, would it be better to look for a rebuild transmission and 'just' swap them or should I plan to do the complete rebuild myself (I never did something like that, but I am willing to do & learn)?
And finally, how much would be a fair price for a car like this?
Thanks,
Mark
