This 1986 Porsche 944 Turbo is easily the highest mileage vehicle I’ve ever owned. Clocking in at over 400k miles, it’s likely the highest mileage car I’ve ever driven. While this needy old Porsche has it’s fair share of problems, it’s still a complete joy to drive. Does owning a Porsche with nearly a half million miles make me a little bit insane? Watch and find out! (Spoiler alert: probably)
