ICBC's Special Investigation Unit launched a probe after receiving an anonymous tip that the brothers were buying used vehicles - some with mileage as high as 460,000 kilometers - and rolling back the odometers before reselling them at a profit. The SIU investigation determined the two were registered owners of more than 300 vehicles over a span of three years.

ICBC said that the brothers typically sought out Honda and Toyota vehicles on the internet or in classified ads, snapped them up and then sold them for a profit after allegedly rolling back the odometer significantly.

The Saini brothers allegedly acted as curbers, people who sell cars and trucks without a dealer's license, which is a requirement of the Vehicle Sales Authority if the seller is making a profit. Curbers often connect with buyers and sellers in public spaces or parking lots, never at their own home, and often have multiple cars or trucks for sale.

ICBC said that a sure-fire way to tell if you're dealing with a curber is to search whatever source you're using - be it craigslist, the Buy and Sell or your newspaper's classifieds - and see if their number is listed with another vehicle.
