Thanks for the info Chris,
The car belongs to the owner of a scrapyard who sell me a few spares for mi Scirocco, and last friday I was there to get info about a an Audi C3 with a 5 cil. petrol engine also a very rare car over here (the high import taxs, avoid us to get a similar car from europe)
But the chances of this Merc are no good, as it is in very poor state, even if the onwer is a Mercedes fan, he uses a w123 as daily driver and said to me that he is thinking about prserve it...
I will be back to see if ther is a plate or other info about the car origin.
An Opel light truck in a barn by the Douro River (Oporto area).
Opel stop sellimg trucks long time agor but by the numbers of abandoned vehicles that stills around, they must be very popular back then.
Sadly I never had seen one restored.
I think one year rebuild time. (I hope :-))
