$100,000 sounds a bit steep. They only cost 40,000UKP ($64,000) to buy the base model (which is all that was available at the time). Admittedly they had the fancy chameleon paint job which adds $2,000 or so.

At least two of the four cars used in the filming were then shipped back to the UK and sold by TVR to customers...
