The shop quoted me $1000 for a brake service. New rubber lines, pads and rotors. I could tell from the test drive that something wasn't right. I figured maybe the brakes needed to be bled. The rotors were all glazed over and so were the pads. I figured the parts on that were the heavy hitter: $600 (maybe I happened to pick out nicer cross drilled rotors

) Either way, I was going to use the shop's estimate in my negotatiations.
Belts are a $700 job, ~$140 for parts. Free loaner tools from a local guy for me to do it.
Tires.... The tires were Toyos. I want something I can drive on the track. You could look at the treads and tell that it was cracked (I didn't see this when I test drove it - shame on me for going when under the weather). The mechanic said they were unsuitable for the track, which is what I'm buying the car for. Owner admitted they were probably a little "square" from sitting.
Thanks for the advice.
FWIW: It's a high milage 1986 n/a 944, leakdown was great. New rod bearings, very dry engine, new control arms, clutch, radiator, (and a bunch of other stuff I'm forgetting).
Edit: Haha, competentone I was looking online at a car in Summervile SC I found on the web. Probably nicer than this one. Too bad I didn't know you were down there. Deal fell apart because the seller wasn't motivated enough to take the car over to the wrench for a PPI.
