Odd that you have all the bags and ESP etc in the Panda but you don't even have an airbag in your TV! I guess you just use your Panda a lot more.
I am only doing city driving so it may not be an major issue, if I was doing lots of higher speed driving then safety would be my main concern.
Well I'd have ABS if TVR offered it, and probably 'bags too. However, the car is much stronger than most people think anyway. The T350 has a built in roll cage too (much better than my old Chimaera which was lovely but didn't even have door bars).
Of course most TVR accidents are single vehicle accidents (i.e. the owner runs out of talent). People see/hear them coming on the road and I find nobody pulls out on me for example.
