should i buy rx7????

yo guys.... ok im not real educated on the rotary motors yet but i know alot about turbos and the reliabiliaty of DSM motors and shit like that... i have a GST now but im tired of that piece shit front wheel drive so my first choice of a turbo rear wheel drive car was the rex. I found a 1987 TII with a few mods done and it looks really clean. The body is straight with no rust, underbody has no gouges or scrapes, paint is ok, motor runs and pulls hard. But i wanted to get you guys to give me some advice on whether or not i should buy the car. Also if you could tell me what to look for as far as problems when i go to check the car out again would be appreciated. heres the link...
