You might possibly find that the chassis behind the rear wheels is rotted or resembles a patchwork quilt
If a garage is quoting £200 to get it through the MOT I suspect it's not worth much
I've been offered a LWB Pajero of the same age for £600 and that has had a new head, has T&T and I thought that was expensive :lol:
If you could do the work yourself then £150 - £225 just remember even with 12 months T&T on it you'll be lucky to get £400 for it
