Maybe need to check brake pad.

Get GX spec instead,  with nicer 4x sport RIM and OEM aerokit.

Of course, extra different of rm 3k price tag if you can afford. Nowadays, many peoples car (called as "2nd wife") already civilized and want to look great with rim(shoes) and aerokit(dress skirting) when ladies go out(on the road). We were in year 2017, not like zaman 1995 - 2015 anymore. People 's demands, expectations and needs have been upgraded. In term of safety features, both G and GX spec quite comparable.

I would recommend to UMW Toyota to consolidate J and E  specs into a single spec,  consolidate G and GX spec into another single spec.Standard nice RIM and Aerokit are compulsory for all variants/spec. For ALL front and rear ventilated DISC braking system, extra airbags and complex advance safety features, only top TRD spec have it, while consolidate G/GX spec CAN have it as optional.People look at safety features, reliability + durable, proven good track experience brand, comfortable, NVH ..etc  when buying a car. Take a look at Altis car, only 3 specs, 7SRS Airbags, GOA body structure..etc. If you can afford, perhaps getting C or higher car segment. Alright??
