2008 GLS na yan bro. Mas mura na mas bago pa. You can upgrade your own Head Unit by yourself. And also you can buy car leather seat covers from MG Square.
IF the 07 MX is with the black interior, I'd get that. hirap i-maintain ang beige na interior. But with your budget, I'll look for a cedia GT. I was hoping for that unit last Nov 2009 pero talagang wala ng brand new.
The Lancer MX cause it has leather seats and better HU than the GLS.
But if the MXs grille is different from the GLS, like the red 2.0 GT's grille as pictured above. And if the MX has red tail lights while the GLS has blacked out tail lights. Get the GLS because it's a more recent facelift.
If they look the same, maybe you can get the MX instead.
