XC 60 Interest

Hello,am new here and had read me some texts yesterday and am now a bit confused because if I have understood this the D3 and D5 are rather worse or more vulnerable because it takes more problems with it even though the Volvo is a very reliable friend it can come to some incidents! The D4 is in this case the better built. Is the right? Search from year 2012 Automatic but not with the zigzag circuit,Diesel I have only driven Mercedes up to now and my last vehicle was a CLA 220 only it has become too small and an XC60 I would like it inside is simple but with still. I live in Austria but unfortunately there is little to choose from and are expensive but also open for a trip to D because I have always bought my cars in Germany. I thank you already in advance for every help.
