Hello to everyone, drive the lupo 1.4 tdi , 75hp and I am convinced PD 3 cylinder flag. have seen this Audi A2 on the way to work….which would be a good thing for my parents….the price is however quite high (see also attached photo)….12.900.-€ is written to the dealer. 60.000km BJ: 2004 have already Googled and the price is normal for the 90ps TDI A2. If still some general questions: 1) on what should I pay attention to when buying? 2) general schwac hen / rust? 3) where were these Audis built (in Germany?) 4) what was the approximately new price of this car 5) is the maintenance / the inspections expensive? ….because aluminium is installed 6) what is the approximately curb weight of the car 7) has the BJ 04 already the diesel particle filter –> so that Euro 4 standard 8) which equipment packages were there? 9) what is the car made of aluminium? 10) is the change of bulb in front itself possible without taking the whole car apart? thank you for your information. until hope soon also one from time to time A2 driver, max
