I did a lot of research on the T350, but work commitments make it hard for me to justify until I change jobs.
Problem with the Tamora, so I hear, is that the Speed6 engine was still suffering issues, of which a lot were ironed out in the T350 generation. The general rule of thumb is to get the latest/newest one possible, as it was continually being revised.
Just remember than the engines are seen as being awesome, but a little unpredictable. You can buy the best, most cared for example, and it can still go *pop*. Luckily, people like TVR Power will do a recon engine with 3yr warranty for about £5k, which isn't bad really.
Alternatively, play the waiting game and try and get one thats had it done - although these are rare - obviously once people have had the work done, they tend to hold on to them!
And last, and most important point - Just buy the TVR. Don't get sidetracked by boring BMW's or Merc's. Part of the fun of TVR ownership is owning something special, different and a little crazy. Just go in with your eyes open and research all possible problems you might face.
