whats a good offer on a 90 turbo?

[j3pz]

i found a 1990 turbo with a targa and 5 spd. its owned by some rich dude but its not in a great condition which leads me to think he doesnt have a sentimental value for it. but bein wealthy and still having a car this old he might. im thinkin of askin to buy it from him, what ya guys say i should offer? the paint is kinda chipped, has worn leather intior, has like 180k on it(i think). the guy is in africa or something so i cant talk to him about it, so i gotta wait for him to come back... im thinkin 3k sounds resounable but bein in high school its kinda pricey. tell me what ya think.
