its really weird how these engines are, i test drove 2 very low millage 172s and they seemed very quick but the prices on them were crazy, a mate got one traded in at the renault dealership where he works, gave me a ring to have a look, 50k on the clock and the thing was mental compared to the other two, was like its got a diff engine, it is a cup and not a normal 172 but i dnt know how much diff there is, i should be picking the car up this afternoon from the dealership yay.
