The answer is a Noble M12 GTO...British (although they may be assembled in South Africa - at least the US chassis are). Supposedly an absolutely awesome track car. Very light weight. They are imported into the US through
1G RACING . They do not include and engine or transaxle. There are several engine options availabe. I think in the UK they are sold with a Ford Duratec V6 with twin turbo chargers. Around $51k without the engine and transaxle.
Very cool car. If I had the resources I would definitely have one.
