Which out of 3 Dash Cam ?

Garmin Dashcam 55 - got 2 of them and the resolution on the 55 is 1440P with a slightly narrower field of view. The 65W is 1080P with the wider field of view. I think the rest of the specs are the same. Except the price. The 55 is about $80 cheaper, on average. Has voice control, and built in wireless pic/vid sharing to a smartphone with the Garmin VIRB app. They'll both record around 8 hours of video/audio if you add a 64GB sdcard. Loop recording over writes at end of file.
I've got 2 of them. So far, so good.

There's an aftermarket (Chinese?) suction cup mount for them you can get through e-Bay for around $12 each, if you don't want to permanently mount the dash cam with the included Garmin adhesive magnetic discs.
