4. Mercedes-Benz W123
The Mercedes-Benz W123 is a shining example of German engineering at its finest. Famed for its overengineered diesel engines and remarkable build quality, the W123 became a staple of taxi fleets from Europe to Africa.
Many of these cars are still in daily service today, with odometers often rolling well past 500,000 miles. This enduring reliability, combined with timeless styling, makes the W123 an icon among those who value longevity and quality in their vehicles.
