I found out this past week that not even the owner of a classic car insurance company can give you a straight definition of what a "classic car" is. While there might be millions of classic car enthusiasts out there, few seem to agree on exactly what a classic car is.

Is it just an car of a certain age like state laws indicate? Is it just cars made between the World Wars? Is it just a select few truly exquisite cars? Or is it simply in the eye of the beholder and undefinable?

Music's "Classical period" is said to be from 1730 to 1820. In your opinion, what is the automobile's Classical period?
