Best suction camera mount for car window

[MJG50 7]

I've been considering making in-car driving videos to demonstrate cars and I've just started looking into which are the best DSLR camera mounts so I can attach the camera to the front passenger's side window when driving. Something like the one below looks as though it could be suitable but I was just wondering if anyone on here who does videos with a DSLR camera could recommend a decent camera mount.

I expect most people use their phones to video cars but my phone is relatively ancient and the picture quality isn't great so I'd rather use my DSLR.

Thanks in advance
