General Comments:

I have a '92 Mercedes E300 as well. It has relatively low miles for an old car - about 92000.

It is definitely the worst car I have ever owned. The best thing about it is that it is safe (I was hit by a dump truck and the car wasn't even damaged), but that's the only good thing I can think of.

The bad things with my Mercedes were that all of the electrical wiring went bad (after research, I discovered that there is a recall for this). The windows do not work, A/C broke instantly, the sole windshield wiper stopped working, and now even the radio stopped turning on.

This car has been more trouble than it's worth. I have to take it in to get it fixed every two months. My mechanic actually told me, "The problem with this car is that it's a Mercedes. If I were you I'd get some good insurance on it and crash it."

I also had a battery explode.

I had one period of time when the car would not shift gears at all, causing it to be non-driveable for 3 months. When I took it to the mechanic, it suddenly worked fine.

Also, I had a MAJOR problem with the alarm system. One day it just started to go off for no reason. At first, it would go off when I started the car, but after doing this for about a month, it would no longer turn off for ANY reason. I ended up having to get the alarm system disconnected.

I have had plenty of used cars before - Ford, Saturn, Toyota, Volvo, Chevy, etc., and none have been as bad as this car. I'm going back to Toyota, which lasted to 300,000 miles.

Nothing has gone wrong so far, so good.

General Comments:

A Mercedes 300e is a very comfortable and reliable car.

It is really great to drive. It feels very solid and safe, and is very quick too. Even today it is competitive.

I bought this car almost a year ago, and every day I love to drive it. I drove it on two vacations to the south of France in October 2009, and this summer to the South of Spain for a trip of more than 6000 km. Also I use it for work and daily driving. With the air con and cruise control on, it was no problem at all to drive 900 plus km a day. Cruising at 150 an hour is lots of fun.

The car is quiet, and the brakes are very good. It feels safe at high speed.

Only two remarks: the car is somewhat sensitive to side winds, and also the driver's seat is not the best you can imagine. There are better seats in lots of cars. It is a pity Mercedes builds such good cars, but does not put good seats in the year 1992.

Also fuel consumption is at a high level. But what do you expect for a car this quick, comfortable, spacious and solid. I take it for granted, and I am planning to keep it for many years.
