Hello cooldog. Welcome. Nice find
There are three garages that specialise in the coupe, one in Leicester (Midlands Car Services) one in Birmingham (Motomech) and then there's the one I use in Upton upon Severn (Fiat Coupe Specialist Services - or FCSS) Joe has resorted a number of my coupes
If you use the search button for any of the above all will become clear.
I'd restore both, I'm currently restoring three. Two Plus's and one 20VT.
Good luck in the way ahead and your link does not work
