Gotta say I'd fancy having one of those V Boxes, supposed the down side would be :
Always thrashing the car to get the best time, speeding and increased fuel comsumption.
Speaking of which Chris said "Fuel economy for the last tank was 22.23mpg " That ain't brilliant, but it depends how you drive it ?
Although I do give the Camaro regular work outs my overall driving style is very economical ( Overall 2nd in the 2001 round Britian Economy race - not a lot of people know that ) current average 27.08mpg.
Just think would you could do with the missing 2 cylinders
