I dislike the cheap plastic that can be found in the car. The cup holders and the small pen holder (which is too small) is made from the same plastic you find in your kids toy cars.
The glove box needs some work, after a while it doesn't close properly, so it appears buckled.
The Parking Sensors switches off by itself from time to time, and doesn't come back on when you really need it. In other words it doesn't operate full time.
The ride itself isn't that comfortable, you can still feel most of the road, although its more comfortable that most cars its still doesn't feel as though its worth the price of £45,000.
The climate control is pretty poor, the fan doesn't blow hard enough when you need it to, for example; it's a really hot day in London, and you car feels like it's an oven. You switch on the a/c it blows as if the temperature outside is mild!!. My E-Class has better a/c and heating than the S-Class. The radio, without the command system, is pretty poor, my shogun gets better reception than the S-Class.
About a year after purchasing the car the on-board computer failed, and so did the wireless key entry. So what does this mean?
Well it means you can't get into the car as the key's battery doesn't work. Also the entire dashboard goes completely black, none of the indicators work, even if you manage to get the car started.
In general the car isn't bad, I guess I noticed most of the problem because I spend so much time in the car. I would recommend buy a Mercedes Benz as the customer care is very good, at least in London. Even though their prices are over the top.
I own s320 Mercedes-benz 2001 with 41500 kilometers only. it died on me while I m on the hi way. my speed was 120 nd I was using the cruise control. it continued turning off every time I start and. it took me one and half an hour to get back home. the dealer engineer told me there is recall on these vehicles, but he did not go into details. i m selling this car as soon as I receive it back from the dealer workshop.
