Go for it. At 200k miles it's still a baby. The E30s were built like tanks and will run forever with proper maintenance, which it sounds like this one has had. I'm laying odds it's got the eta motor, tuned for low revving torque, vs. the i/is motor with higher revving horsepower. Great drivers and great handling with minimal mods. Heck, if you don't want it I have half a mind to buy it, too bad it's too far away for me.
