Karl, Having done something similar to a MB 190, I wouldnt recomend it unless you or whoever is doing it has done it before and has worked all the bugs out of the process. I was not satisfied with the results, however ther are people I am sure that could do it and make it look awesome. The hardest part is mating the two and dealing with the interior afterwards. Again, I am an amature...so mine sucked. But $$$ was an issue at the time. Does anyone know how difficult it would be to take the metal skin off a non sunroof car and pot the skin from a sunroof car on it? the sunroof shell I have has a bend in the roof, so it looks like using the whole roof is out of the question.
