have you ever seen a $100,000 Duece

Never heard of a Chevy II being called a Deuce - a regional thing, maybe?

Deuce = '32 Ford to me (as in 'Little Deuce Coupe').

I wouldn't say that. Calling it just "deuce" is a tad unusual. Generally, you'd hear is called a Chevy deuce (or Nova) and Ford deuce so people can tell which one you are referring to. Personally I call it a Nova which the same as the Barracuda and Cuda, same car just one was standard the other performance.
