I'm looking for a project car that I can drive to work and thrash around autocrosses on the weekends. It has to be a manual, RWD or AWD, and not a Miata (because I don't fit in one). My budget is around $10-15k US.
I've been looking around, and I'm sorta down to a 300ZX or a Supra. Which one should I choose, or have I forgot something?
You have to ask yourself what your ultimate goal is. Have fun at a local level? Trophy at Nationals? Blow a small fortune staying in a stock class? Or blow a larger fortune in a mod class?
If you just want to have fun and don't care where you place, then get whatever makes you happy.
If you want to win, then the first you need to do is decide on a class. And how far you are willing take your competitive urges. Once you decide what level you want to compete in, the decisions virtually make themselves for you. If you want to go to Topeka and go home in a fancy jacket, then you want to see what the winners are running.

So beyond the S2000 and Miata already mentioned in your price range, there is:
RX-8
(Cayman)/Boxster
Mustang GT
Corvette
and Mini if you open it up to FWD
If you can't fit in a Miata, the RX-8 may not work for you either, especially with a helmet on. Look for a Touring or Sport with no sunroof. Cayman is out of your price range, but 15k will snag you a nice 986; just make sure you check the real main seal for leaks. C5 Vettes are a total bargain these days.. just not many in a manual, you'll have to look around.
15k will also get you into a pretty clean E36 M3... with some research and preventative maint. I really don't see why reliability would be a concern. What sorts of problems did your friends have?
For an decent auto-x car, skip the B5 S4. Good street cars, decent track cars... not very good auto-x cars. You'd be far better off with a WRX or Evo.
Old men try fruitlessly to hammer their monstrous Corvettes through autocross in vain attempts to beat Miatas. Good luck in a car twice as wide. Old Mustangs and Camaros are popular - particularly when they're stripped and shod with 11 inch wide tires, because that's the only way to mask their glorious handling deficiencies.
Same for the Corvette really - the handling characteristics required to be stable at 170 mph are totally different than what you need in the tight, quick transitions of an autocross. You need a front end that is quick to respond and has massive grip, the Miata being one of few cars that doesn't need modification to achieve this.
Depends on how open the venue is. A chapter that is stuck with a tiny lot will naturally end up with courses that play to the Miata's strengths. If the course is open and fast, then the old guys have no trouble getting the times down. Just look at last year's Nationals results. And the front end responds just fine and has plenty of grip, sounds like you've never driven one.
