Guess you should've had a V8, lol.
At least you didn't get to experience the plastic coolant tubes splitting and dumping coolant all over. That would have completed your Cayenne adventure.
My least reliable was a Fiat 128. It ended up as a goat playhouse filled with dirt on a farm in Northern California.... goat cheese yum.
