Top car will start to loudly beep and light up the dashboard like a christmas tree with SERVICE NOW!!! warnings whenever the windshield wiper fluid is low, seat belt is not fastend or a brake light is out. Has controls for radio and clima hidden 3 levels deep behind a touch screen interface. Comes with an app that will somehow stop working after 5 years when the car is no longer sold, or after you upgrade your phone. Has a subscription that allows you to go faster and use the heated seats you already paid for when you bought it.

Bottom car will run as long it has fuel, dosnt judge you like a fuckin audi would and lists engine oil as "optional" in the manual.
