Which is a better car?

I own a 2004 Mercedes and I love it! It's luxurious and drives great. The maintenance is steep on them as well is the gas but if you can afford a Mercedes you shouldn't worry about little things like that. My mom has a BMW and likes it but she agrees a Mercedes is the prettier of the two. BMWs are more of a sporty performance car while the Benz is a luxurious cruiser.
