£550 with rusty rear arches and a rusty drivers wing. I did the front end last year, 2 new wings, 2 new valances and various other panels were replaced which were taken off my parts car which I paid £100 for. I did not photograph this bit but here is a picture of the finished job
Last year I picked up 2 brand new Toyota rear repair panels for the princely sun of
£370 off Ebay, these are superb pieces of kit but are quite large. 
In January I decided to start removing the rear panels, so with a combination of spot weld cutter and drills I set about my car, passenger side first.
The rot was worse than I thought so had to replace the inner arches as well, Toyota no longer do them but MK3 Fiesta inner arches from Beevers were quite close, but still require some cutting.
Next I had to repair the rear of the sill, and then fit the new panels.
I decided not to put the whole panel on as it runs into the top of the roofline so I cut the panels to fit behind the rear quarter light vent.
After much spot welding and sealing it was done.
Next to the passenger side, I was lucky that the inner wing on my parts car was OK so I cut it out and welded it in 
The rear of the sill on this side was worse but fixable
Then the new panel was fitted
The bottom corners of the rear valance both had to be replaced with new metal.
..
And then the guard under the rear floor was removed and POR15ed and tidied up in general
While I was down there I replaced the suspension bushes with poly and had the arms powder coated
Next big problem was the top of the windscreen, I had the glass removed
(came out in one piece) and discovered why I had a leak I had no metal left.
After some more welding and filling and some POR15
....
Then it was off for a respray
Here are some of it when I got it back
(skirts are back on now), still needs a really good polish but am going to run it for a while and let the paint harden 
And finally a bit of Marmite, I am not sure whether I love it or hate it
You decide
