Phil: I'm assuming you mean are they two different models of TVR, as I'd be worried if you weren't sure of the differences between a silver car with little silver wheels and a number plate, and a grey car with big anthracite wheels, no plate and different badges, lights etc
Mine's a Chimaera, a sort of GT version of the Griffith of the early 90's. TVR's best selling car, with around 9000 cars being produced. That and the Griffith were TVR's glory years, with simple Rover V8's (that sound louder than they go) brilliant styling for the era and brutal 0-60 times.
(The bit of styling around the front indicators isn't deliberate....TVR always mould their cars from clay rather than sketch them. The director's (Peter Wheeler) bit a chunk from the front and they left it on the mould!
The grey one's a Tamora, one of the later cars made after the Tuscan where the Director of TVR decided he wanted his own engine in the cars, otherwise it's just a kit car apparently! And again, apparently, a British sportscar should have a straight six, so they developed a Spped Six engine with over 350bhp for the Tuscan...the lairiest TVR made. later, they introduced a softened version called the Tamora, with easier handling and a slight de-tune. It was a bit easier to drive, and as designed to rival Boxsters. But the looks weren't everyone's cup of tea (the back isn't a work of art) and people didn't want to spend everyday german sportscar money on unreliable British fibreglass coffins. So they only made 362 (IIRC). Silly fast though, that particular car has taken a De Tomaso Pantera with ease, a Lambo Countach and a Ferrari 360.
Ian: Yes mate, a combination of mis-diagnosed faults sent me up the longest garden path ever until recently, where with the aid of the ever legendary Doc, the problem was worked out and solved!
Tim: I never smile.
