Your opinion on the best looking one?

Sup guys, I'm interested in buying my first car and so far I've come with 4 candidates may I say. Btw, the only common aspect these 4 cars have is the price.
So, there's :
-2013 Mercedes CLA(without the AMG styling packet which kinda sets it back on my list a bit),
- Mercedes E-class Coupe from 2011
- Bmw 5 Series from 2012
- Audi A5 Sportback from 2012
I would appreciate to hear what you think of those cars both in general as well as regarding the looks.

Audi A5 will be best as see it's features and sales records.

Also irrefutably the best looking interior.

I would take the A5 if I were in your shoes. To me, it's the best looking. I am a fan of sharp angles and aggressive fascias, and the A5 boasts all that. I also have a thing for engines of small displacement but with big power. I'm not exactly sure what the power stats for the A5 are, but I do know that Audi designed the car to be well balanced, in terms of power and fluidity, so that it's not underpowered. At the end of the day though, the decision is up to, so make the right one. Factor in what characteristics you like in cars (speed, power, sound, practicality, brand preference, design, interior, etc...) and you'll be certain to land in the car that's right for you. Good luck in purchasing your first car. I have yet to do so myself but I hoping to grab an older model sedan (an Audi or a 89' Mercedes 300). Once again, good luck.
