The XP-737 Sebring Spyder roadster was built in three basic versions by GM Styling, all based on the same car and all with a wheelbase shortened 15" from the stock 108". This is the second version, the first one shown to the public. It debuted at the Chicago Auto Show on February 18, 1961.
Dayton wire wheels were used on it and other Corvair show cars before the stock Corvair Kelsey-Hayes wheels came about in 1962. Its engine was boosted by a Paxton supercharger, like the unit still on the Super Spyder. The rear wheels were noticeably de-cambered since the car didn't have to cope with rear passenger weight.
The Sebring Spyder bumperettes inspired Cal Custom to produce similar aftermarket bumper kits, which are rare today. The instrument cluster was the prototype for the production Spyder unit. And the entire rear deck was one fiberglass piece hinged directly behind the seats. This was later replaced by a stock deck lid and a rear-hinged tonneau that hid a real folding top in the car's last version.
GM Styling Archives state that the Sebring Spyder was scrapped in 1966, but one never really knows for sure... so far, it hasn't surfaced!
