Oh crap, you're trying to access 15+ year old memories, since I sold it in like '84 or '85 (let's see, do I keep the kids or the "fun" car?).
As to fitting in it, I'm 6'1" and it I didn't have to put the seat all the way back, so it's fairly roomy.
As I recall, the shifters are naturally a little "sloppy", so I wouldn't be too worried if it seems a little loose. It shouldn't be hard to find the correct gear as you up/downshift though. There shouldn't be any grinding (as you already know, I'm sure).
I don't remember any real problem areas, leak-wise. Check the boots on the transaxles. I remember having to replace them and repack the CV joints a couple of times. Now that you've brought it up, I may start remembering things, so I'll post back with anything I can think of. Since I've been out of it for a while, I'd wonder about parts availability on cars that have been out of production for so long, but perhaps since there's still a lot of them around, it's not a problem.
You may find some info here. This is the club I belonged to, but of course they didn't have the website back then:
