He saw an opportunity to use technology and data analysis to create a better car buying experience. In more than ten years, CarGurus has become the most visited car shopping website in the United States1, with more car listings than other major online car markets in the United States2 also operates websites in Canada and the United Kingdom. It began trading on the Nasal Global Select Market in October 2017. It will give each car a rating from "good" to "expensive", and sort the search results in this order. Great deals from top dealers always rank at the top of these search results.
