Once you decided what brand of vehicle that you want you have to decide what model. Almost every year that brand that you like comes out with a new model of vehicle. Therefore you have to choose one. I chose a beautiful model on a Used Mercedes and it it black. I love the color black on vehicles so when I first bought my Mercedes I made sure that it was black. Choosing the model was not that difficult for me because I have liked every model that Mercedes has come out with so far. I love my Mercedes and am glad that I chose this model.
