The chassis and engine are Triumph Vitesse 2LT but I can't seem to find another car that matches mine. At first I thought it was a Spartan but it isn't as this is all made out of fibre glass. DVLA have it down as 1958 Triumph.
That's an interesting photo. I've never seen one without the 'S' Type Jag rad style grill, but as with all kit cars the builder makes his/her own choice.
