Here are the differences:
VX=Plain, no value added features
LE=It's a VX with F/F A/C
VXR=F/F A/C, and value added features such as fabric seats, fabric door trim, wheel caps, matching bumpers. No stereo.
Buy a VX, and put NipponDenso A/C and Dunlop/Bridgestone tyres.It will cost about the same as VXR and cooling/roadgrip will be better.
++ black bumper is easier to maintain.
