2. 1955 Mercedes-Benz 300 SL
The Mercedes-Benz 300 SL was the first iteration of the SL-Class grand tourer. It was based off the Mercedes-Benz company’s successful racer, the W194. What made the 300 SL unique were the distinctive gull-wing doors, first ever production fuel injection, and the world’s fastest top speed (at the time) of 161 mph. The engine was derived from a DB 601 V-12 engine, used on the high powered Messerschmitt Bf 109E fighter from World War II, Mercedes raised the output from 175 horsepower to 215 horsepower, almost double to horsepower of the original type 300’s 115 horsepower. The technological firsts, gull-wings doors, and low production numbers makes the 300 SL one of the most collectable Mercedes-Benz models, with prices generally in the $1 million to $2 million dollar range.
