Faults:

Generally the car was reliable in a certain way, because the engine always started, and the brakes worked.

Rusty.

Electronic seat's memory never worked.

Electronic seats would not move some times.

Transmission broken - $7000.

Touch n' go broken several times.

Leather on the backseat split.

Air-conditioning was very slow.

Radio never worked, bought some Chinese crap for $180 that worked much better.

General Comments:

Mercedes-Benz made the car good for first impressions only. When I first drove it, the car was the most comfortable car I ever had driven. The impressions of the V8 were very good, when driving on the road it was quiet, and when pushing the throttle, you certainly got what you required.

After 1000 km.

When hitting the throttle for an acceleration from 80 to 160 km/t, it surprised me that the gearbox took 2 seconds before it shifted down, and that was a pain, when you wanted to overtake a truck.

It started early to get rusty; I found some in the trunk, and then it got worse. When I sold the car there was rust everywhere, and it was only a matter of months before it thoroughly corroded, and then you could take it to the dealer and complain.

Faults:

The automatic gear stuck in first gear three times in the 3 years we owned the car. It is really annoying, especially if you have to drive a long distance to get to the workshop, but to fix it you have to restart the car's computer, and last time I changed the transmission oil, there were some pieces of the metal in there, the mechanic said I would have to change the gear soon, which cost around 1400 US for a used one.

The parts are really expensive.

The audio system is only OK, and the radio receiver is kind of weak.

The response of the car is slow, especially when you use the kick down (around 2-3 seconds).

Till now I do not know how to let the air enter the car through the fan without turning the AC on.

General Comments:

It is a great car, really reliable, that does not break down much.

If you know how to drive it, it is kind of economical. The best time it gave me around 300km/20l (35 mpg), worst is 180km/20l (21 mpg), average is 220km/20l (26 mpg).

Faults:

Everything under the sun; you name, it seems like every month something goes bad, whether it's a turn signal, glove box latch or bulbs...

General Comments:

This is not the car for someone who does not like spending their life savings on maintaining it... You need really deep pockets to keep up with THIS baby... I guess hence the name Mercedes Benz...

Nice comfortable ride.

Transmission starting to go at 100k... everything else is great; the ride, the mileage on gas... only thing that sucks is the amount of money you have to shell out every time you fix the darn thing.

Faults:

Things that had to be fixed/replaced during my nightmare ownership (in no particular order):

1) Alternator (twice)

2) Had to rewire car because it didn't meet Canadian regulations (warranty, but this is pretty ridiculous for such a car)

3) Rust on door

4) Transmission rebuilt at 50000kms ($4000)

5) Replaced dash display

6) Steering fluid reservoir BLEW UP while driving

7) Moon roof broke ($3000)

8) AC condenser broke at 80000km ($3000)

9) Right headlight due to water and mold damage

10) Both taillights due to water and mold damage

11) Rust on door

12) Multiple sensors

I kept this car in a clean, dry, indoor garage. There are many other problems, in all it cost me over $30000 on maintenance and repairs for this car over ~8 years. Service is really bad too, I would not recommend this car manufacturer to anyone I like.

General Comments:

This is seriously the worst car in the world.
