Well, lets look at it like this..any time I need something for my GTS it cost an arm an a leg, so yes I do have an idea of how much this could cost..let me give you an example..just to import a gen 2 viper to Norway, would cost you about $100.000 + in taxes alone..and that is not counting the fact that you first have to buy the car, pay for shipping to get it here, pay for freightforwarding fees in the US and Norway, get the certified papers from Dekra in Germany to license it..then you have to do the modifications to make it fit the European DOT standards, and finally you have to go through DOT inspection to get it aproved on all points that DOT requiers to give you a licenseplate to drive it legaly on the road.
Maybe a NASCAR motor is not so expensive after all.
