Mark salesmen are notorious for telling us tall stories to make a sale, remember we can cancel right up to the day of collection.
If the car doesn’t have the features or options promised then don’t put the PIN number in and walk away until they can fix the problem.
Again salesmen will say anything to make us put in the PIN number as then we’ve excepted the car, it goes down as meeting their target for the month, then they can take their time changing stories on who said what, hoping you back down and make do with the car you have.
