Dude, don't buy a TVR, they are absolute garbage. Poorly built, naff 'Kit car' fit and finish, chassis rust out, rear wishbones rot from the inside and colapse and they're so unreliable its funny- we get bored counting the number of TVRs with the bonnets up on the way to Le Mans every year.
A good friend of mine bought one two years ago, brand new, looked great and went like stink. 3 weeks in it broke down and went back to Blackpool to be fixed. It spent 7 of the first 12 months back at TVR in total. After breaking down for the second time in as many days (after 3 weeks back at TVR) he got out of the car, called the dealer and told them where the car was and walked away leaving the keys in the ignition. He then spent months and a fortune in legal fees before he got a full refund on the car. He now has a 3 year old Carrera 4 which is just fantastic if slightly dull.
Whats your budget Jez??
