Now onto the car as seen in pictures, if there is rust in front of the rear wheels, it is common, but can get pricey to fix, also looks as if it needs a complete paint job and some body work. Get rid of that style bar asap, if you need a reason google miata mouse trap you will thank me for this advice. if you want a roll bar look up hard dog, boss frog, true roll bars not style bars. wheels should definitely be a make or break thing for you, you can generally get a set for 500 give or take off of the honda crowd. 4x100 bolt pattern wouldn't recommend bigger than 16's. parts are fairly common for these cars on forums like this so whatever its missing chances are somebody has one laying around. i generally check if anyone has a part im looking for before i try to get it new from a parts store. The radiator looks fairly new, you can tell this by the color of the plastic tanks. if they are black its fairly new, when they age they turn a greenish brown color and that is when they are about to go. i would also ask for the original air box, believe it or not that cone filter hurts performance because it pulls in warm air, mazda did a fairly good job with the stock one.the top looks to be in fairly good shape, the vinyl rear windows fade over time to the point where it is very difficult to see out of, keep that in mind.
To some it all up i would try to work it down a bit due to condition of the paint, and would see 2500 would be a good price in my opinion. hope this info helps you in your search for a miata.
