I have only driven cheap used cars but it was good because it help me to save a lot of money, now i am thinking of treating myself to a luxury car, there is a 2007 s class mercedes that i can get from a dealer for $30,000, now what i am worried about is how expensive is it to maintain a car like this i dont want to be throwing away too much money on maintaining the car so for you getbiggers who owns a luxury car how much do you spend on it yearly.
