OH dear Theo you didn't fall for the ole Towmaster Commodore Cup track trash chat did you??
That's OK we've all been there!
No mate, my Dato does not have PS. My cobra does though. I believe some of the later DCS did but I think if you ran conventional you'd be back dual pulleys. As far as electric goes I'm not familiar with that set up at all but I'll have a look at mine over the weekend just for giggles and see.
The previous owner ran about a 20inch steering wheel so perhaps he felt the need for the power assist? I quite like the stiff feel. With the narrower front tyres its easier but not so much an issue for me.
If I find anything interesting I'll let you know.
