I've easily spent 10 grand fixing up my RAC van so far... (Although it had a new engine at 95000 and just had a new turbo so I'm happy I stuck with it.)
A steam cleaner was also amazing for shifting the gunk and making the seats nice again.
It's good you've got some panels left - could save you a few pennies down the line
