Mercedes-Benz 300SL Gullwing

The 1954 300SL was the world's fastest production car and the first to use fuel injection. Its iconic gullwing doors weren't a styling choice — the tubular space frame chassis was so tall-sided that conventional doors wouldn't work. Mercedes built 1,400 coupes and 1,858 roadsters. The 3.0-liter straight-six with Bosch mechanical fuel injection produced 215 HP — revolutionary for 1954. Today, Gullwings are $1-2 million cars and the crown jewel of every serious collection. It's not just a legend — it's the car that made Mercedes-Benz a sports car brand.
