is the vinyl cracked?  could they be cleaned up with a magic eraser?  id run it as-is until the winter when you can start tearing stuff apart.  if the seat frames are needing to be replaced you can disassemble them and cut new... hell id make new seat bases for someone for a lil coin...

I can get the interior done for 650.00 for the bench and bucket seats if your still interested. text me or call me at 602-386-0771.  We can also help out with new wood for the seats if you are wanting to wait until the season is over, which would be roughly 950.00 for seats and vinyl.
