for those who think TVR is a new marque, here the Griffith from the mid-sixties, fitted with a 4.7 V8 Ford, then and now terrorising the Cobra's during GT races, when it lasted, which was and is not too often.
To be different I would choose the TVR, for quality reasons the Porsche which you can drive for more than 5000 km's before things start falling off.
