13. Saab 900

The Saab 900 stands out for its unconventional design and sturdy engineering, qualities that become even more pronounced with age. After 400,000 miles, the 900’s sloping windshield and quirky profile gain a distinguished patina—faded paint, worn leather, and subtle quirks—all enhancing its eccentric charm.
These visible signs of a long life are celebrated by fans of automotive oddities, who see them as proof of the car’s resilience and individuality.
As Petrolicious notes, the Saab 900’s appeal only grows stronger with time, making high-mileage examples particularly coveted among enthusiasts who appreciate something truly unique.
