This is good because appart from a few people with dailyish drivers, my Vette has travelled more than 30,000 miles since I bought it in 99! And that includes only about 200miles in the last 2 years(Dooh, and not my fault), so if you'll let me discount the last 2 years thats an average of about 3,800MILES (5600km/year in a Big Block!!!!!) SO 497 average cubes divided by 3800 average Miles = a number of 0.13, so the lower the number (closest to 0) is the winner! CPU are u a Mathamatian? does that compute??? Average cubes Divided by average miles/yr??????. bonnevista will probably win?
