Hey! I resemble that remark!
Parts prices aren't bad, cheaper than the 911 for most stuff but once in a while you run into limited supply parts like a distributor cap, for $90. Parts availability hasn't been a problem though, you just need to know where to look.
Cheap to buy not cheap to own so like a 944 you'll find many neglected examples. I bought mine pampered w/21K on the clock and it's been relatively problem-free. 'Buy the best one you can afford' definitely applies here -- the best being maybe 7K. $7700 is way out of line for this one.
My biggest problem with the car's been DIY support. If you're a mechanic, great, there's the factory service manual but for the layman there's no Haynes/Chilton and certainly no 101 projects.
