I have a clean rx7 with a motor that blew the front water seal and therefore was parked. I traded for a motorcycle a few years ago, but haven't looked into it.
PRO's
Clean chassis
Entire motor intact
rotor assembly good (apex seals ok)
Aftermarket suspension/exhaust
Clean title
CON's
Not running.
I can post pics or you can just take my word that it is a very clean chassis and just bring the cash when you come to pick it up.
