Looks: subjective

I have an elantra 1.8gls and I'd choose it anytime against Lancer EX 1.6MX and the previous Lancer EX 2.0MX

Pero for a 1.6, I'm leaning towards Lancer 1.6 GLX AT, considering that I dont usually modify my ride's exterior. And when it comes to tuning, mas maraming tuning option si Lancer.
