I built an Opel GT back in the late 70's. I found an abused 1973 and started from the ground up. Parts were tough to find so I started buying up every derelict GT I found. Ended up buying 8 of them over a period of 10 years. I started a mail order used parts business in my spare time....Oh to have had the internet back then! Life changed and the GT had to go. Saw 5 GT's rusting away in a field last week. Made me sad...............
