In most modern Toyota cars, you'll find a visible Vehicle Identification Number through a special cut-out at the bottom of the windscreen. Additional VINs are printed on tamper-proof stickers located just inside the shut line of the front nearside door. Earlier models may have a metal plate instead of a sticker. Moreover, you can use a vn decoder to find the information about the car you own or are planning to purchase, here s the website
