Saml666 ... I had a Griff 500 for a couple of years - superb fun ...
At least in this weather the thing will start when warm after filling up with petrol
Mine was a pig when the starter solenoid overheated every time we went out - a characteristic of the car ... well known ... but not by me until it did it the first time !!
Nothing beats a TVR for sheer grunt and fun - mine was fairly economical too - 18mpg for the performance on offer I thought was pretty good.
