Guys,
I came across this link the other day
http://www.kitcarz.co.uk/its a very detailed build diary for an Extreme 360 and the guy really tells the truth about the full build, good and bad points.
As he seems to be a very practical car building guy, he mentions early on about what a dangerous car builders can end up with unless, like him, they add lots of extra welding and safety features not detailed in the DVD...how many builders do that!
Anyway, its very interesting and if you have a some spare time its worth reading (im only up to about the 4th part!)
