Old brands do sell...otherwise there wouldn't be a new VW Beetle, for instance. It borrows a bit from the past...but uses modern common technology under the hood (VW Golf), instead of a boxer four cylinder rear engine like the original. So why not buy a VW Golf instead, it's the same car basically?
And if someone buys a new Beetle and tells about it on some internet forum, there's a mocking party gearing up at the vintage Beetle forums?

I think there's room for all camps, all publicity is good publicity and all camps gain from it.
