Welcome to the forum Mattpoke, and of course traffic.
Not familiar with that particular Bitchsumishi car, but you should probably look at a dual channel system ( front & rear )
you should also look for the Sony starvis 2 sensors named IMX 675 for the 1440p resolution model and IMX 678 for the 4K model
You also want a system with capacitors in it for EMG power source, batteries are not good in your northern location as they dont handle cold and heat well.
Also you should get a 256 GB capacity memory card for the camera you choose, one that is compatible with the make / model
A good way to get in the game could be one of Viofos previous models ( just being replaced now ) the A 229 Plus and PRO ( 1440p and 4k )
These are still very much valid systems, and by now bug free/ dialed in, and as new model A 329 are launching now, you should be able to snag a good deal on the older models
You can browse those model sub forums to see what people and testers of them think about them, sadly i have no personal experience with that vintage of Viofo models.
