I agree with the age related plate idea, but when I found my donor vehicle it was advertised as a pinto sierra on ebay. The old owner drove it to my brother in laws 150 miles away from me. He said it was running ok so I got transported to my house. Would you beleive it was fitted with the old crossflow engine the sierra was imported from South africa.
However I like the engine and it is simple to repair and maintain. No problem with spare parts yet! So I have decide to keep it, maybe I'll change my mind after the IVA.
