Could you put that Opel GT on , maybe, an S-10 4x4 chassis ? That would be unusual...
Funny you should say that.
I'm currently on my (I think) 17th Opel GT, Technically it would be 16th and 17th since I have two of them.
BUT, my very first one, I sold in a moment of desperation. A few years later I saw it in someone's side yard and they had, indeed, put it on a 4X4 chassis. And just like every other idiot did in the mid 80's, they thought it would be cool and then abandoned the project halfway through.
How did I know it was mine? I had a one-of-a-kind paint job on mine. NOBODY would be crazy enough to do that paint job. Part of the reason I sold it was someone damaged the paint and there was absolutely no way to repair it without stripping the car. And I wasn't about to do that again.
