The seller replies to messages, and is happy for viewings. If I was after one, I'd want to see the documented service history, and when the seller bought it (as per the V5), and if that all checked out I'd go and see that car, and see how it drove. I can't see it being a ringer; the colour is too rare.
I rather like the steering wheel, and those bumpers look just fine to me; surely they're only 'wrong' for a Sport? I don't think it's a Sport anyway; the headlamps are wrong, as are the bumper foglights, for a facelift 211.
