I took my 2011 XF in for service and got a 2018 as a loaner. I really prefer my own car for several reasons.
It is quieter. I don’t know if it is because the loaner is a turbo 4 AWD and mine is Naturally aspirated V8.
2, It is harder to get in and out. The rocker is higher and wider than on mine,
It seems that mine is quicker.
