My sad experience with MacBook Pros has been with the death of the display. Apparently, the cables between the keyboard and the screen have a tendency to be stretched, the consequence is nothing but several columns of psychedelic colors. If you are very patient you can find an angle between the display and the keyboard that results in the display working as expected. The drawback is that much of the keyboard can’t be used unless you have very small hand and even then the magic angle gets smaller over a few weeks until no use at all can be made of the display.
Googling will reveal a long list of complainers whose MBP‘s have lost the use of the screen shortly after the coverage period. Within the three-year coverage period Apple Care will take your MBP and give you a new one, but when that MBP develops the same malady, you’re out of luck. Repair cost from Apple is some $500, but independent and authorized repair shops may charge less. Let’s hope the 2020 M1 models have found a way to avoid the display issue.
BTW, if your display dies you can replace it with a monitor. It isn’t very portable, but even <$100 will buy a useful monitor that plugs into a USB-C port. You can close the lid, but then you’ll need a camera and a Bluetooth speaker & microphone, headset, or Air Pods, as well as a Bluetooth or cabled keyboard.
