The good thing about Nascar is that it has a controlled field. It takes a skilled driver to win the race, not a faster car. Auto Action recently did a price comparison between Nascar and V8 Supercars and the price difference to build them is austounding. All beit that Nascar is oval track and runs a steering box still but it is a budget sport believe it or not. A car cost approx $250K to build then maintain. V8 SC costs abou $1 Million to build them maintain. IT all comes down to the blueprints of the car build. V8SC are trying to make the cars more cost effective and reduce overheads to make it a more viable sport as it seems to be heading in the same way as the AFL.
