Audi S5, BMW M3, or benz c63 amg for undergrad student?

Are these cars suitable for a college sopre..my fraternity brothers are informing me otherwise..they don't think it'd be a good choice to start with something that "fancy"...but i've always had fancy cars growing up...my first car when i was 16 was a 2002 3 series..nothing special..but I wrecked that car twice..lulz.
