I have been wondering about this since Le Mans when i looked at a left hand drive Sag. Seeing this picture in the classifieds has just reminded me to ask if anybody knows what the extra buttons do on the Gear Tunnel? Don't think i have ever seen them on a right hand drive car before?
I have them on my T350 too, one button is for the dylithium chrystal pre-heaters and the other is only for ex-terrestrial use, slowing the car down to a suitable speed for re-entry.
Thanks guys typical of TVR me think it was for export only on Sags and we now find UK TVR's have them as well! Personally I thought they were for the Hyperdrive system and Parachute deployment
