FindTheBest, an information site that lets shoppers compare everything from apartments to dogs to venture capitalists, is adding classified ads for cars, apartments, jobs, and pets.

The new classifieds fall into five straightforward categories: Cars for SaleJobsRentalsDogs for Sale, and Cats for Sale. According to FindTheBest, outside partners vet all of the data to cut down on scams and false listings.

FindTheBest uses data and statistics to compare schools, electronics, apartments, travel locations, and more. Comparison metrics vary widely between each category, but there is a focus on graphs and icons. For example, laptop ratings include a colored bar that shows processor size and colored arrows for the screen size. Automobiles include a circle for the gas mileage and a colored bar for the horsepower.

Now alongside the comparisons between those 2010 and 2011 Rolls-Royces you’re secretly lusting after, there will classified ads to buy said luxury cars (a few people are actually selling a Rolls, if you’ve got around $300,000 to spend). FindTheBest brings the same icons it uses for the comparison side of the site to the classified section. For example, the Rolls-Royces each had colored squares to indicate their odometer readings.

These new classifieds will contend with Craigslist, a well-used classified listings site. As anyone who has used Craigslist will tell you, it’s full of scams, spammers, and classifieds that often lack relevant details. But it’s also a very popular site to list all sorts of stuff, including jobs, apartments, tickets, furniture, electronics, cars, and services, and it’s a stiff competitor to any other classified services out there. FindTheBest’s classifieds could become more valuable because they are full of information that Craigslist listings lack, such as prices, background information on the item or service, and contact information for the seller.

FindTheBest has raised $6.76 million to date, including a $6 million first institutional round from Kleiner Perkins in July, 2011. The company is based in Santa Barbara, Calif. and New York.
