C70 offer and then disappointed

Had from the official Volvo side an offer of a Volvo dealer for a C 70 D 3 Aut Summum, Xenium for 29900 Euro.EZ 04/2011 with 16600 km. After 240 km arrived there my wife first noticed that the bonnet had no symmetrical seat, i.e. the columns on the sides were different wide. My question whether this car had an accident was immediately negated. Next, my wife noticed that the windshield was without Volvo stickers, so probably not an original part. As if then the parking aid wanted to try out, which should be available according to description in front and back, it hit at the rear, while it did not make any mucks at the front, although its activation was displayed in the display. After again careful viewing, we could neither identify any sensors at the front, compared this again in the car house with other vehicles and were confirmed by the fact that there was no fault in this vehicle. My question about the windshield was dismissed, that it was probably just as unimportant as the question of whether the Aral or Shell did wrongly take the replacement for me at the front.
