i get on average 34mpg and i drive mine very mixed driving local and motorway
normally get about 230miles to a tank unless motorway all the time then can be more just depends how fast you drive.. stick to sub 100 and your laughing.. over that you can watch the needle physically dropping

but then you dont own a v6 for mpg but the grin factor of that growl
love my st200 and not had one issue with it yet.. the horror stories are made to sound a lot worse than they are, just think about the thousands made and actual problems.. no worse than any other car.. TBH i see more RS's broken down on the side of the road than V6's
oh and the mk3 v6's apart from the 220 are still using the same v6 as the mk1 and mk2 so they cant be that bad can they
