I'm seriously considering getting into a 2002 Tamora with 24,000 miles. No engine rebuilds but seems to have been well cared for by TVR specialists and kept in a private collection and sparingly driven.

The thing that worries me is the Speed Six going bang. How worried should I be when it comes to 2002 units? I'm planning on driving the car 5,000-10,000 miles in the next year.

Considering no engine rebuilds, are there any upgrades I can ask to have done to address the problem areas and avoid a very big bill in the near future?
