Fantastic at bringing other's designs to life, and indeed at designing for others, W&P never did produce their "own" car, despite tentative discussions with various potential collaborators over years. The closest that they got was with the "Sebring" and "Sebring GT" ranges of full fibreglass bodykit for the Austin Healey Sprite and MG Midget, along with a range of transformative hardtops for assorted British sportscars of the sixties.

The W&P Sebring GT Register was started in 2008 to document the surviving examples of this very pretty bodywork, and is well supported and recognised in the Spridget community. Over time it has expanded to become the full Williams & Pritchard Register, but these pages are for the enjoyment of those spridgeteers and Spitfire drivers whose relatively humble cars (compared to much of the other exotica on the Register) were the inspiration for this website.
