Solved- NEH 356: Ghia Ford Marbella - 1974

[Carnut]

Everything is possible here!

Maybe Vizcaya?

Well, there aren't that many Spanish cars that have been named after Spanish towns/cities; to my knowledge Vizcaya is not one of them!

Malaga?

Malaga is one that has been, and is close to the solution (geographically) but is not the right one.

Ford Marbella by Ghia

This however is it!
At last we've got there, it is indeed the Ghia Ford Marbella built in 1974 on Granada mechanics to investigate the possibility of a separate 2+2 coupe for the European market.

I told you that clue would get you there and it's a mystery to me why it wasn't followed up on earlier.  There was an easy point there for the taking!
Well done.

Barcelona?

As I said the name had been used for another car by a different manufacturer!
Just remind me who made a car called a Barcelona?!

There was a Maybach W3 Limousine bodied by Kellner and called Barcelona...and I believe an Hispano Suiza H6B Weyman Sedan called that way too.

And we all remember the great Mercury Barcelona, don't we?

Since it was based on a Granada I suppose it was appropriate name this development of it on another Spanish town..

Here are some un-retouched pictures of the puzzle car:
