Snow Mobiles: a Fitch modified Corvair Sprint (for sale)

I saw the car at Motorland in Arundel, Maine last week of March.  "The Corvair Fitch Sprint was a set of modifications for the Chevrolet Corvair automobile developed by racing driver John Fitch. John Fitch was given the opportunity to test several models of the brand new Corvair and he then set out to develop various engine, chassis and body modifications.''
