Nice to make your acquaintance. I bought my GT at 22 years old and have spent 22 years with it, great car! If you have any questions bout it, feel free to ask. Currently it has a 2.4 liter motor out of an Opel Frontera from the 90s (same block as the 1.9 liter) Bosch Motronic fuel injection, a 5 speed trans from a mid 80 Opel Rekord, BMW front brakes, Chevy S10 clutch and Renault master and booster. Whole car is rewired with a modern fusebox. Needs new exhaust, but there is always something.
The cars are still out there and are not too very expensive. You can call Todd at Opels Unlimited or Opel GT Source and they can sell you anything from parts to a whole running car. Let me know if you have any questions.
All I can say is WOW! That is some mods you have done. I am more that impressed and envious. I keep looking but to tell the truth I don’t know if I could get in one today. When I bought mine I was just out of the Army and a lean, mean, will you get the idea. Must say that I sure turned the ladies heads back then, the car not me.
