I watched this last night, I'm going to say it's still not worth £40k (minimum) for some off the line speed which you'd only use a few times at best unless you take it to the strip etc...
It's all down to grip for the FWD, part of me thinks that they didn't have the best tyres on it, or being the UK the best surface.
Still like is mentioned at the end, VW won't let the Golf be beaten after the MK3 being "better" round a track.
