It isn't just about being fast though is it?
Big, Fast, Loud, Close racing, Recognisable drivers.
If you can get all of these elements you're onto a good thing.
Personally I think it would be great if V8ST drilled holes in their exhaust
I'd be interested to know how people rank these attributes.
For me it is:
1. Big
2. Fast
3. Close Racing
4. Recognisable drivers
5. Loud
Let the debate begin!
PS - anything else that is really important?
