Volvo V60 or XC60 ?

Hello dear Volvo friends, I wanted to get a Volvo soon and as the title says, I am thinking about what’s most useful. Starting point: For my budget I get either a V60 with 15,000km or an XC60 with 90,000km. Both diesel with 163hp and the XC is already 3.5 years old. (Both cars have Volvo Selekt) I live in an area where four-wheel drive is worth it (mountains, lots of snow in winter). On the other hand, I have concerns about the 90k km … not that the engine is over after 1 year … I don’t know how to handle the car. What do you think ? mfG Hora P.S.: Does the V60 actually have an electric tailgate ? And is this in the XC60 series ?
