All new car there come with winter wheels/tyres.
Only if you order them. And a lot of people don't.... then go and buy aftermarket ones for a fair bit less.
So there are no longer part of the price of the car?
Ah, now your asking the right questions.
The same questions Im always asking when the Warning Triangle is absent on a UK Golf but present on a the same car bought on the Continent.
New car dealers are just upgraded used car salesmen imo, and get up to all the scams they think they can get away with, especially if the manufacturers dont keep a tight grip on them.
Eg; no triangle, no saftey vests, no spare bulb kit, with no first aid kit, nothing too much trouble when your buying or haven't completed the feedback form but cold and dismissive thereafter.
Ive even had my 'full tank of petrol' run out in less than 50miles from one dealer yet be told and received a 3/4 full tank with my latest motor.
Likewise advertising, I will not display a dealer advert across my back window or on my number plate surround, they must pay to display if thats what they want.
My present dealer knows what I think and omits all such advertising, which is better than watching me remove it all on their forecourt I suppose.
Excuse the rant but I feel that when you buy a quality product you have a perfect right to expect a level of service of a similar standard.
