honestly how much diff between the cars, which one get which off the mark, which one gets the top end trophy?

from stats obviously the vtir, and i can bet the vtir, but by how much?!

or does the vtir only rev out an extra 1k giving it its extra?

im looking to buy one or the other, i want a vtir ... but i can afford a gsi easier and vtir's are much more rare on the market...
