What about a 1957 Porsche Speedster (replica)?

There are many manufacturers: Vintage Speedsters, Beck Speedsters, Intermecanica, etc.
I had one made in 2001 for four years made by Vintage Speedsters in Hawaiian Gardens, CA. I paid $18,000 used, kept it four years, and sold it for $16,000. It's a fiberglass body on a shortened VW-pan, has a VW engine (from 1600cc - 2600cc. mine was 1776cc and fast) so it's cheap to buy, cheap to insure, cheap to maintain, etc. and a blast to drive. I sold it last year along with my 2005 Mini Cooper S Cabriolet to buy my dream car....2002 Porsche Carrera Cabriolet.
