Why aren’t more vintage cars being reissued?

Jaguar produces the D-Type: http://www.sueddeutsche.de/…/…ml-dpa-com-20090101-160323-99-327742 Aston Martin does similar things: http://www.auto-news.de/…/…ation-reprint-of-a-legend_id_39441 (unfortunately only for the race track) Why is something similar not done more often? If Mercedes would re-build the 300 SL, for example – they could ask for any price, so it shouldn’t fail, right? One more step: couldn’t one take legendary bodies? n and build the rest as a modern car with all the amenities of today? Corvette C3, E-Type… Sure, you would have to change a lot for passenger and pedestrian protection, for example. But the hood of the E-Type looks pretty pedestrian friendly, for example? But there would be no hurdles that would not regulate money, wouldn’t there? Wouldn’t it be nice to see these “eye-catchers” more often?
