only had my is 200 for a couple of months and even though im old enough to know better i took it up to 120 mph on saturday and if the wife wasnt with me i might have carried on, but how fast will they go? it just doesnt seem to struggle to find the power, also ive been using v-power petrol from shell ,£60 to fill the tank and almost 400 miles, some people seem to be complaining a lot about fuel consump but i think its pretty good for a car you just cant drive slow
