My mk4 (180bhp) had 130000+ and just seemed to be getting quicker and quicker,,, .
So when I test drove the mkv I put it down to mileage,, Plus you don't know how it's been driven before.
Plus when I think there is only 20bhp difference between them both and I "think" the mk4 is a little bit lighter...
Still happy with the car though,
took me a year to find one in the spec, colour, I wanted.
