After this time it may just have come to having to just break the golf for spares

After looking at it, rust in quite a few places of which an inner sill, a large hole in the floor, a hole in the rear quarter and a hole on the boot sill amongst other places! The first thing my mechanic said was it isnt a very nice one, although looking very nice on the outside!
I think I have put about £1500 into the car and cant afford to put any more into to get it up too scratch. After all you buy on body work and I can see it needing another 1k into it.
Is it best to just scrap it after I have removed parts? I would give the shell away after finishing, if someone thinks they can recover it ( you need welding skills!)
I can see myself getting around 1k in parts from it over time. I couldnt see anyone offering me 1k for it as whole!
I'm so gutted
