I had a VX220T before my scooby and remember being unable to shake off an ordinary looking, but probably modded classic on a slip road joining a motorway. Lightness certainly helps, but as others have suggested, with its 200bhp standard tune many scoobies will keep up with it.
Power isn't everything though and what made it so special was the feedback it provided and preecision in handling. I'm surprised that Duncan wasn't too impressed on that front, as my VX handled beautifully and was so easy to place on the road. Perhaps the one he tried wasn't set up well. I had mine set up by plans motorsport, who specialise in lotus and VX and their geo changes utterly transformed the handling.
