What is the best vehicle for me?

I'm choosing from 4 vehicles, 2012 infinity g37 sport, 2014 mustang gt, 2013 Chevy Silverado, 2008 bmw m5 e60? I've just turned 18 and I have a decent job. Just getting ready to upgrade from my old Ford Focus.

You'll wreck the m5. Leave that for a few years.

On a 1 to 10 scale, with 10 being the best:

8- Chevy Silverado

6- Mustang.

3- Infinity.

.05- BMW

Really? You can afford one of those at 18? Impress "easy" girls = Mustang. Impress "classy" girls - BMW. Likely lowest repair costs = Infinity.
