In general the E30 325i is a very reliable car and will very unlikely leave you stranded, unless you neglect the obvious. The main maint points over a Jap import would be the the 60K mi interval timing belt and valve adjustment. Other than that, the typical, powersteering seems to always leak and go bad.
It all depends on what you are looking for in a car. If you don't care about perfection and don't mind a little leak here and there, the E30 is a good choice for reliability. If you like perfection, it'll cost you to find or restore one as they are aging and appreciating quick. What else can you get for that price? You don't have much to loose if it all looks and sounds good even if you decide to scrap it, should you decides it's not worth the cost of the repair. in other words you can try to run it to the ground and still not pay much as the car dies of something. On the other hand if you want to do all you can to make it last, you'll be spending the same kind of money as you would any other used car with that mileage. Without prior history, plan on, at the very least flushing/changing all the fluids, and that's not trival in effort and cost.
Does this car have a manual transmission? Automatics don't seem to last as long and not worth as much.
based on the photos, it seems the color is/was Bronzit, unfortunately one of the least desireable colors and it looks to have been painted since the color is more gold than silver. the front air dam is bent and the lip is missing, but all that is cosmetic. Make sure it didn't have serious body damage and signs of leaks in the interior. Looks to be in respectable condition. How's the interior? Any signs of wear?
