First of all i want to say that you are making a really good decision.
Well b/w GL and GLX thers only cosmetic differences really.
I would opt for the GLX cause it has one of the best interiors in its class.
Basically if u want to be practical get the GL or otherwise GLX. But the good news is (as u prbly already knw) the prices have come down so it would be even better to go for GLX , now its 1lak cheaper.
My cousin has the GLX and basically i love it. Infact i give him my Steermatic and drive the Lancer myself. Ride is great , interior ofcourse , . good brakes. Unlike local cars thers no squeaks or rattles . And it just feels different.
Only one thing , wit the A/C pick is'nt so good but thts the same with all 1.3L i.e Corolla , City etc.
In the city it gives him 14km/l without A/C. but keep n mind the car has done over 10000km . In the beginning it will do less.
Dnt knw how it does on long runs , prbly 16-17km/l,
Parts are expensive but are easily available.
Its probably the best 1.3l in Pakistan. Go for it.
