Just to add to the confusion, some earlier diesel Cloverleafs were standard 150bhp without a Q2 and without the Sport button.
Later Cloverleafs had the Sport Button, 170bhp and the Q2 diff fitted.
Blacklines came in 1.8 and 1.9 form. I might have dreamt it, but I might have seen a 2.0 one as well....
If you want true limited edition appeal, get a Q2, the actual Q2 spec GT, not a GT with a Q2 fitted as an option.......if that makes sense!
