www.knology.net/~jediklc for parts.. he's a good friend of mine and usually has parts cheap.. even if the part isn't listed, email him and ask what he's got.
Spring/shocks are cheap as crap, but if I were you, I would just see about getting the camber fixed. Lowered cars handle better, and the tilt of the wheels is called a "camber" which is why it's wearing unevenly. You can usually pick up a camber kit to fix it with for about $100 max.
And watch out with that growing on you thing.. they're like a cancer or something.. they stick to you and then before you know it you're completely obsessed... I've owned 5 of them, ranging from a little ol' base model to an imported JDM (japanese spec) racer.
A/C probably just needs a recharge. shouldn't be more than $50. Check the yellow pages for a shop that does A/C recharges.. if it's something more than that, HIT ME UP.. I have a whole A/C system (no hoses) just sitting here and I need to get rid of it.
And about the oxidized paint, you'd be surprised how much the appearance of the oxidation can be minimized by a good detailing. Spend a day on it.. break out the clay bar and the swirl/scratch remover.. a good detailing is gonna take you about 8 hours, but it's so worth it when your car is spotless.
Yes, I would say you got a good deal.. 95 is probably the most desired model year, and the miles are low for a car that old (most places assume 12,000 miles a year average).
OH YEAH!! VERY IMPORTANT! Find out if the timing belt/water pump/belt tensioner/accesory belts have been changed. If they haven't, DO IT IMMEDIATELY. There's nothing worse than snapping a timing belt. It'll cost you about $550 to get it all replaced at the dealership, but you should be able to find a local shop to do it a bit cheaper. You'll save a lot of money if you work on your car yourself, so I'd recommend a Helms manual (the one for the 92-95 civic and del Sol). It's about $60, and the same manual that the dealership guys use. Definitely a good investment. No use spending $100 on labor to change a starter (for example) when you can do it in your driveway in 30 mins.
Last thing, welcome to the world of owning a sol. Check the FAQ for some good sites to bookmark.
