why do our people always destroy such cars???
at least it is in safe hands now (i hope you live up to expectations now buddy). i'd suggest you start by stripping her and rebuilding all the body correctly and then gettin grid of all the rust etc. once you have a good frame to start with then (and only then) will you be able to build a good car on top of it.
you're one of the lucky few who has a decent coupe in PK and this car has legendary status in japan so there are MANY parts available for it and many websites dedicated to this particular model.
Levin (PW member) will be able to guide you in this rebuild as he had one of these cars when they were new and also has allot of experience in restoring cars in PK.
i know that finding parts for this car in PK is a nightmare but it can be done.
