Its against the law to go above 70 so no problem really. Just a bit less MPG

I dread to think what the original 1.2 8v's were like on the motorway, they only had 4 gears, sitting at motorway speeds doing 85ish it would be sitting next to the redline lol

First, lets get the thing out the way that 'motorway speed' isnt 85. Motorway speed is 70.
Second, the reaosn you get 25 mpg at 85 is because your foot is probabaly almost to the floor in a 1.2 which kills your mpg. My 1.4 8v averages 43mpg+ at a steady 70.
And lastly. A 4 speed corsa would be doing 3,700 rpm at 70 and 4,500 rpm at 85.
