The median 2020 BMW M4 in the Canadian market sits at $64,299. That's your anchor. If a car is priced anywhere near it with reasonable mileage, you're looking at a fair-market number, not a bargain and not a rip-off.
Most of these land between $59,896 and $71,007. That's a wide spread, roughly $11,000 from the low end to the high end, and it tells you condition and options matter a lot on this car. A well-kept example with the right boxes ticked pushes toward $71k. Cars below $60k usually have a reason, so read the listing carefully before you get excited.
What the mileage tells you
The typical 2020 M4 out there has about 63,792 km on it. If you're looking at one with a lot less, expect to pay near or above the top of that range. A car with noticeably more should sit at the bottom, or below it.
