I usually trade a vehicle in after two years or so...cars are toys to me, I get bored easy, and I always want the latest shiny new toy that comes out.
That said, I actually still like my 2018 Macan GTS, and I just might keep it longer than two years, but will definitely trade it in before the standard warranty expires.
