Connected car in the second-hand lot? Don't buy it if you're not hack-savvy

They car should automatically delete any old 'key' or paired device when a new one is entered. If you want to sync multiple devices there should be a small temporal window where all devices need to be present to check in. Any other method simply means that when you drop your car off with the valet or mechanic or whatever the car is exposed to being connected with any number of devices beyond your control and without your knowledge. There's no need for the car to be second hand, all that's needed is access.
