it's a heavy vehicle so if you don't like spending much money on gas you should read the gas milage before you purchase. Overall other than that it's a great. It's heavy, rides smooth, and it's a benz so kind of dependable. I am not to crazy about electronics in general, but it has all the features that you need if you a techy person. Navigation system its very good, keyless entry, keyless start, plenty of room for the whole family and more, 7 seats really work good with family with small children. Its one of the safest vehicles on the road and with the weight and the airbags system, well, it's definitely my choice of vegicle for a road trip with my young children, considering safety first. As I say gas milage is not that great, but safety is my concern so I deal with the gas. Service to a good service place as I have Pardos in west chester is good, if you choose the dealership it might be expensive, so if you decide to buy this car, find a good local mechanic/ service center.
