MPG, if you drive it sensibly (yeah right LOL) it will do 25.
To drive, its VERY responsive! Pulling away normally in traffic you have to be careful cause touching the pedal just makes it want to leap forward!

You will really struggle to find one under 80k, however mine has done 76k, I paid £8100 for it.
Mileage isnt really an issue unless its over 120k on original turbos
