You've got more chance of being bitten by a daffodil than finding a cheap TVR V8. Most tend to have panel damage which is quite easy to repair. Chassis damage is expensive. V8 engine , gearbox and ECU tend to go for about 5K
Cheapest I have seen for a while

TVR pre registered a lot of cars in 92 to get around the emissions test. Pre 93 cars don't have a cat and sound much nicer.
