it also depends on whether you change the colour of the car. If you want to change from Black to White, it will be more expensive.
For satria, RM1600 is consider cheap, of course it also depends on the workmanship.
Try to send to those paint shop equip with the machine to "bake" or "dry" the paint.
Some will just leave it dry at open air for 2/3 days, dust will attach to your new paint surface in this case, which is not good for your paint.
happy painting :)
