Any straight two door Escort shell (Mk1 or 2) is worth silly money these days due to historic rallying.
Then mix in a genuine AVO shell and you are on-route to a big spend.
I visited a workshop recently with the prospect of supplying a Paint scheme.
The owner had a section of his building full of FORD stuff, one item been a MK1 two door rolling shell, I was knocked off my feet when he suggested he had refused an offer of £10K for it, but suggested if I had £12k I could own it, it wasn't until I returned home and did a bit googling that I realised he wasn't mad
