Mercedes-Benz 300D Reviews
I own a 94 european model imported in 97. Best ever hands down, it even has the fire-extinguisher system under driver seat. Starts right up, handles, accelerates and handles great.
The 1993 Mercedes Benz 300D is the best car I've ever owned. Not only is it a fun, smooth ride, but the engine is practically immortal as long as you do routine checkups and quick fixes. The fuel efficiency is epic for an early 90's vehicle. I average about 30mpg driving like a maniac, and that's with some throttle problems as well. Also, mind you, the fact that you can use SVO and WVO to power this baby.
It may be old and slow by today's standards but it is absolutely fabulous to drive and built like a tank.
