America has jumped at several opportunities to own a piece of the past, even though many were loose translations, but has ignored others. Some manufacturers like Mini stay true to the original while others like GM and Nissan interpret retro-modern a different way. What is the recipe for success? Do some designs fail because they’re based on vehicles too old or obscure to appeal to a wide range of consumers, or do customers walk because the design isn’t faithful enough to the original to make the association? For every retro-modern car that collect dust on dealer lots, others become big sellers and with Baby Boomers retiring with more personal wealth than any generation before it looks like the retro theme is here to stay.
