Tamora purchase advice please

[jmn]

Thinking of buying another TVR-I have previously owned a 350i and Griffith 500.

I have been trying to find out what to look out for with a Tamora and have come up with these items:-

Engine-I am aware of the potential problems. Is it correct that a later car from 2005-6 is likely to have a more reliable engine if correctly serviced etc?

Diff bushes-I understand that these can be a problem. How can you tell if they have gone and what is the replacement cost if done by a specialist? Any known problems with the diff?

Radiator. What is the replacement cost on the same basis?

Anderson Connector. Replacement cost?

Clutch. I understand about £1k to replace?

Chassis-presumably this can rust just like other TVRs?

Instrument module pixel failure-what is the likely to cost to rectify?

Any recommendations for expert inspection in the London area?

I expect there are other things that I am not presently aware of so advice from those 'in the know' appreciated.
