BMW Diesel Touring BJ 2007 / 2009

Hello everybody, I am currently looking for a new vehicle. I drive 35 km to work and 35 km back every day (almost only the motorway). In addition, there are the normal private rides. Since my father drives a BMW 320D E91 BJ 2007 and I have noticed that this vehicle is also a lot of fun for me and it is also suitable for my work path, I have looked up two vehicles and made dates for test drives. Now I am researching tips on driving on the following Article of the car picture pushed:http://www.autobild.de/…/…3er-e90-brauchtwagen-test-5593425.html Here it is already described, that with the models quite problems can occur. I look at the next days the following cars: BMW 320D Touring 120 KW BJ 07/2007 163 PS AUTOMATICS with 202000 km BMW 318D DPF Touring 105KW BJ 04/2009 143 PS AUTOMATICS180000 km. and as a cover: Audi A4 Avant 2.5 TDI S-Line 120KW BJ 04/2005 163 PS AUTOMATICS 195000 km. Audi A3 Sportback 2.0 TDI Ambi Question: is it better to leave your fingers off the BMW (especially the 3 series). Are these cars more suitable for short distance or as company cars with maintenance contracts and less for private ones? Are the listed problems normal problems that occur also with a VW, AUDI or Mercedes or are they especially common for the 3 series? So that an AUDI would be more advisable? Even if the BMWs look class, it would be even more important to me an A uto buy, which can be driven without big problems. If further questions come up, I gladly answer these ncoh. Many greetings Caliber
