I admit it was'nt as bad as yours but it was a few years ago, it was a 90 spec RST in grey metallic, which needed

Battery tray + bulkhead repair panel
Back panel like yours
Pair of wings front
Front lower valance
Full respray except for the roof
Repairs to the drivers seat
Full valet inside and out
and a few mechanicle bits sorting

there was quite a bit of work involved but i got it cheap and even after all the work it had done it stood me less than an average condition one, and when i sold it i actually made a profit and was inundated with calls as it was the best available at the time, so my advice is stick with it and onward and upward mate....
