LEGO Technic car stand and wall mount

I haven't found a satisfactory stand for my LEGO cars, one that could display cars on shelf at an angle and possibly be wall-mountable that wouldn't be tied to just one set.

Cue my solution: elegant design that fits standard LEGO peg/connector pin in 5x11 studs layout. So it can mount any and all sets that I want to be displaying and has 2 screw holes for mounting to a wall.

BOM:

• A LEGO Technic car with suitable connections on the bottom
• 4 2L pins/connector pegs with friction
• 4 3L pins/connector pegs with friction, 2 2L pins with friction, 2 11L Technic beam, 1 5L Technic beam (see images)
• 2 M5 screws for wall mounting (at least 30mm in length with suitable wall/wood anchors)
   

Intended mostly for the ultimate cars series: Ferrari Daytona SP3 42143, Bugatti Chiron 42083, Lamborghini Sián FKP 37 42115, but is universal to any LEGO set in general that matches connector layout.
