EZ and BJ = 1999 but model year = 2001

Hi, I found a SLK on mobile.de, which I would like very much myself with automatic: [http://suchen.mobile.de/…/showDetails.html?…]my SLK?[/url] a) in general, what do you think of this? What can it cost maximum? b) how can this be that the car EZ/BJ 1999 is a facelift model and should come from the model year 2001. I asked the seller this question and he scanned his invoice on which the model year was confirmed, according to his information it was a press vehicle from DaimlerChrysler Many greetings and thanks Andreas PS Need your opinion as quickly as possible, as the VK will hand the car over to Daimler on 8.6 at the latest, unless he can sell it beforehand
