No problems at this time.
The ride is comfortable, making a long drive seem like a short one.
In car entertainment is all you will need, with six compact discs to choose from for a start.
The engine does have a habit of 'screaming' when asked to accelerate quickly from a standing start.
I think 1000 miles is a little short for a review of the car. Lets see how it goes after say 10,000 and then come back to us.
I own a 2000 ML320 with 40,000 miles on it. It is an absolutely great car, powerful and safe in practically all terrain. Only problems have been changed brake pads twice and uses gas like no other. However, it is a great car that has never failed me once and I would definitely recommend buying from MB again.
