Impressions from the offer and the official car dealer:
Probably it is something common but some detail of the specifications of the car were, in my view, implied... like seat belts. Well, the description did not mention seat belts but had specified thing like: electric heated back window, fog lamps (front and back), mirror in the passenger side sun visor (one can get on the drivers side as well), headlight (seriously).
Then in an upgrade package: color-matched door mirrors (shell I read that the basic package gets color mismatched mirrors or...), colour-matched side moldings...
Well, these are only small things but I was a bit confused what happens to things I assume implied and was not mentioned - spare tire, light in the glove box, jack...
