1990 Mercedes-Benz 300SE Reviews
Beautifully solid and quality car. Every line on its body has purpose, nothing is clumsy or mediocre. Nice extras like all the little map lights, leather everywhere, everything that is wonderful about this car makes up for the things that take alittle extra money or time to maintain. A well maintained 300SE will last a million miles, a neglected one will be a money pit. Make sure you buy one...
One of the best Mercedes ever made. This is my third Mercedes, the 1990 300 SE, and I am about to spent $4000 to get a paint job. Car runs great and I have only 160000 miles. The design is truly classic. Elegant lines going to a great front end. Can't wait to see it like new and drive it for the next twenty years.
