Here's a Perry Design (Perry D) pseudo-Spyder for sale on ebay for $15k starting bid. Perry D uses a VW pan so engine is in rear just like a bug or Spyder. He doesn't know it's a Perry but that's the only Spyder I know of that uses VW pan. Sure this compromises handling a lot. Car has a stoked 1900 cc engine (since when is a 69 mm crank stoked?). Also supports smart "fun" - most of my fun is from dumb stuff.
