"All around satisfied. Except for 2 issues. #1. The stock tires don't last more than 25K miles. Plan on spending over $1K to replace and you have limited options. Hankook is your best option with guarantee.
#2. Mercedes doesn't hold it's value as much as Mercedes likes to tout. It is a great quality car, few if any maint. issues, comfortable drive -- but depreciates just as fast as other cars. The real win is if you keep it over 7 years...then you see a difference."
Pros: "Diesel, great gas mileage, large towing capacity"
Cons: "Too many sensors, expensive tires, gas cap issues"

"I own have owned this vehicle since new and I am on my 4th set of tires. The original factory tires lasts less than 15,000!!! Absolutely unacceptable. Only tire manufacturer is Parelli and these tires are extremely expensive. After 3 sets of Parellis I now have a set of Hankook tires and these are the best - reasonable in price, aggressive tread pattern, etc.
As for the diesel engine, it is the only way to go. I get well over 600 miles per tank. I drive from Raleigh, NC, to NYC in one tank and I do not need to refill until I am in NJ where full service gas stations offer the cheapest gasoline (and diesel) in the Eastern US.
Too many sensors on the vehicle is a curse and a blessing. Fuel filler cap does not close when the outside temperature is very high - another annoying fact.
Otherwise a fine vehicle which is aging well."
"If looking for a great big SUV this is one of the best. Traded and it brought 2/3 of its original value after 4 years! Turbo Diesel engine was flawlwss, and yielded lots of power torque and quiet sophistication, and up to 30 mpg on the highway! Amazing, understated luxury, impressive to customers I transported."
"I just switched from a Lexus GX-470 to a GL 450. The ride is much better than Lexus and is more roomier. However, the instrument panel needs a major overhaul. This is the first car that requires you to read the manual just to find out how to operate the radio/CD. Once the radio is on, turning it off is yet another challenge. If I hit the power button, it turns the entire COMMAND off. The panel is over complicated. Why do I have to read the manual to operate such basic tasks???
There should be ONE button to do these things. I have to hit several buttons in the panel before anything starts."
