Another contributor (Micky) took delivery of a CLA Shooting Break recently and was really stuffed by Mercedes, as the car was really a Premium, not Premium Plus, as it was missing so many features, yet he was still asked to pay the AP for the Premium Plus. I think that 99% of people, under normal circumstances, would have rejected the car, but in the current climate with ridiculously long lead times, dealers have customers over a barrel – and know it. If certain features are important to you I would double check that the car has them fitted before you accept the car by entering you PIN. You can reject the car at any stage, right up to that point.
