There is a lovely one for sale at APS in Brackley - a 3rd Black with an Akra.

3dr makes that cool. But by sound of description it sounds like it has no options at all... nearly £29k is a lot but that seems to be what they're all going for atm in that mileage round (27-35k miles). I still can't believe I got mine for 26 in March with 30k miles and loaded spec besides sunroof (which i wasn't interested in anyway). There really aren't many good ones on the market, let alone many full stop. Something will come up soon I am sure
