First of all thanks to tsikot for helping me in my decision between a 2nd hand and a brand new car. I have just closed a deal with BPI for a 1.3j brand new Vios. I'm really excited to get the car this week.

Im comparing a side visor accessory one from a toyota dealer and another at blade. To my surprise, the price difference between the two is really big. One set at the toyota dealer was selling it at P4,000 while the set at blade is only P1,300.

Question:
1. Why does the price difference is big?
2. Does it have to do with quality?
3. Does anyone have experience with the side visor from blade or toyota?
4. Does Installing third party accessories void the warranty?

Note:
The side visor from blade will be ordered and will be available after 1 week. Therefore i have no idea what it looks like.
