The key is to communicate our passions. Grammar and syntax, it is only when we can. Are you referring to "Opel GT" 2-door coupe 60s or "Ascona GT" like mine? The former is easy to find if you have more than 10,000 euros at least. The second is rare with a little mileage and without a rust spot. Often many kilometers. There are also some Ascona GT Sport but only 1,600 cc. Only the name is Sport. I had one (a 2 doors) in 1986!
