I miss my Opel GT.Had a 1973 5-spd but never got it past 110mph as no one I knew of could properly adjust or repair the carb.Years later a fellow related how he found warping of the mounting was the issue and having the mounting surfaces milled flat again cured the tiny air/vacumn leaks that prevented proper adjustment.But I had already long sold my GT after a family member wrecked it and I was unemployed and unable to afford the repairs. Have not seen any in even decent shape in a long time.Looked at a couple advertised and found rusted junkpiles on inspection.
My parents had the Opel 1970 station wagon and it was thrifty of gas and easy to drive,park , and still carried a LOT of stuff.Local GM dealers didn’t want to be bothered with Opels.
Although I miss the GT ,the Opel Manta was also a sporty little car but more practical with seating for the family.
My Fiero is the out-of-the-ordinary car now,and it won’t rust!

Sorry, I think it’s a late 60s Opel.
