[Devon300zx]

hey, im new here and i posted on craigslist that i wtb a rx7 and this guy messaged me with a 1988 turbo II, i know nothing about a rotary engine, i just want to know what are some things i need to look out for. the he is asking for 2500 dollars and it has "68000" original miles supposedly, the body and interior are alittle rough, i also want to know what a car like this in this condition would go for
