Peter Ellis was/is putting a large resource of Tenth Technology info together -

I'm sure he would have a good idea of top drivers who used to drive the older models. Ive got lots of info on them but Peters probably got all that and a lot more. Im sure if you PM'd him he would be able to help you out ?
Also, half the 'more experienced' racers on o0ple probable drove a 'Legacy' Predator at some time in their career

Just in my region Dave Belsten, Chris Mills, Russel Williams and Craig Harris used to run XK98's/ETQ's/P8's at some point, and they are all current or ex F1's & 2's so pretty good drivers themselves....
