Several manufactures are now offering some functions of the vehicle as subscription services, which typically come with a free trial period from when the vehicle is new but that require on-going payment at some point. While these subscriptions may not be mentioned by dealers, the terms and conditions of the sale will outline what is and is not included as standard, so we would advise reading the all the small print before signing on the dotted line. It is worth mentioning that these features are typically desirable extras and that the vehicle will still operate without them, but more clarity from dealers would be a benefit to customers.
