I just bought a 1971 Opel GT a few weeks ago. I have wanted one of these for several years and I have been casually looking in the papers and such for a while. I finally found one for sale Locally in the Denver area so I bought it. It is silver and in really good condition. It needs some work, but that is to be expected. Firsts things on my list are to fix an oil leak from the oil pan gasket and the Trans pan gasket. Then I am tackling the electrical gremlins that keep my gauges moving all over the place.
Anyway I think this site is a wonderful place for all kinds of great information.
