The quality, price, and smooth ride of the car all the time and anywhere you go.

It is technologically advanced. Besides lane assist it can parallel park by itself!

I love my red Mercedes SUV! It's roomy to fit all the things I need to haul around. I love my sunroof and the safety features are awesome. Lane assist is my favorite.
