"I bought my GL550 new in '08 in black with tan premium leather and traded in my CLK55. I got Heated rear seats, keyless go, dual entertainment screens. This car has ton of room despite the fact that the trunk is should be slightly wider. The seats heat up in 45 seconds! This car even has massaging seats! This car was loaded even without options I added! The engine is a horse! The 5,500 lb SUV goes from 0-60 in 6.5-7 seconds! The engine is super loud and in the GL550 you can barely hear it! I highly recommend this car."
"NEVER BUY a Blue-Tech. I bought this car in expectation of towing a trailer and still retain the style and comfort of a luxury vehicle. For the most part the first three years were great. Once that 40000 mile mark hit, I have had nothing but trouble. Terrible, and now as soon as I leave the shop the [Check Engine] light comes on again. What? Another $600 for a motorized intake valve. Not to mention untold other issues like $6500 for possible transition replacement. Then the Blu-Tech heating element is only sold as a combination piece with the entire unit. What $1200? Now they tell me the oil is leaking... on a Mercedes? The worst car I have ever had. Door closes like a tank, but it drops maintenance fees from my account like a rock in the ocean. Oh, and by the way my father bought the E class Blue-Tech. Same type of issues. Garbage. We have had Mercedes for years, but never again!"
"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."
