Our daughter has just purchased her first new car (slightly smaller than yours, a VW T-Roc) and I strongly recommended (insisted?) that she install a DashCam for her (and my?) piece of mind.
It looks like my (almost non-existent ) wiring and trim skills are going to be called in to hard wire it in, as she was informed that running a front and rear DashCam from the 12v cigarette lighter socket was going to draw too much current.
As you say a very worthwhile investment on today's roads.
