2010 Mercedes-Benz E-Class E550 2dr Coupe (5.5L 8cyl 7A)
This car is a rock star to me, they got everything right, even the little details from the LED running lights to the engine growl. I had a S500 that pampered me, but this one is just flat out fun to get into and drive. I have had it almost 9 months and haven't had a thing wrong with it. I don't use the navigation much but when I do I can tell there is a bit of a learning curve. It is fun to have a car that generates second glances and let's you know you have more than enough power on the road. The 550 engine was well worth it.
The styling and the engine are top of the line. It is just tough to imagine them being better. The upgraded leather in the Launch Edition package are impressive.
Maybe the only thing would be to allow the moon roof to be tilted when the sunscreen is closed to allow venting on a hot day.
