The spoilt of choice: A2 factory car

Hello together, with interest I read the posts in the forum. Stand before a difficult decision: Would like to afford me an Audi factory car. The A2 completely convinced me – what I have read and heard so far – but on the one hand there are many concerns about the factory cars and on the other hand about certain special equipment (Open Sky). I have two cars in the short choice, maybe you can give me tips: A2 1.4, 66kw 7000 Km, 07/2005 Acustic Parking System Driver information system Seat heating in front and then the usual Advance & Style –> about 16.400 Euro A2 1.4, 55kw 8000 Km, 08/2005 Driver information system Acustic Parking System Open Sky Handypreparation BOSE loudspeaker lumbar support electr. Sidelight Radio “Concert” Seat heating in front of steel winter bikes Winter package + Style and Advance –> about 17.500 Euro The 90 PSler would be ideal, but the only 1100 Euro more expensive 75PSler is of course ingenious from the equipment. The Audi original already costs 500 euros (according to the catalogue). BUT: I have heard of so many problems with Open Sky, have they slowed down with the last series? Also the fog lights should be at risk of breaking. How are your experiences (except for what I have already read) especially with the newer series? Of the resale value the second is certainly the best. But I have no desire (and with such a high investment no money left) thousands of euros for the repair of the roof s to pay … or how long does it run on Kulanz? For tips I would be very grateful!!
