What do I have to pay attention to when buying an Alfa?

Hello, I want to buy another car in the spring. It should become a used Alfa 147. What are the typical files I should look at/test? Where does the car have its flaws? I like an Alfa like this one here:http://www.mobile.de/SIDLXH9clro.Tgc8Cl80C4Q9g-t-vaNexlCsAsCsK%F3P%F3R~BmSB11Iindex_cgiJ11355074797A1Iindex_cgiD1100CCarW-t-vctpLt~BmPA1A1B20A6%81_-t-vCaMiMkQuSeSnUnVbZRZi_X_x_ycopo~BSRA6D1100A7C900AGCPKWA1A1A1HinPublicB50E8836 4A2A0A0A0ADC110/cgi-bin/da.pl?sr_qual=G&top=2&bereich=pkw&id=1111111179364732& Can you tell me what this car uses so typical of gasoline, perhaps also with respect to the models with a smaller engine? I hope you can help me. Greetings Freehawk
