Uploading photos, typing in comments, picking the year, etc., is easy Being able to pick options and things that make the car unique is very hard- most of all THEY are going to assign the price and if you don't like the price they assign, they give you a lower ranking like a "fair deal" or or lower. If you go along with their price assignment, but you don't buy extra enhancements from them, after two or three days they lower your rating to a "fair deal" or lower when absolutely nothing has changed with the car. For example, when I questioned them about why after the third day the car was listed they arbitrarily changed the value rating from good deal to fair deal, they closed the listing and marked it as sold! It's not like the service is free - if you sell the car you pay them, which is fair. But all the other bull crap is not Don't waste your time using CarGurus! I wish I had screenshots of my listing, you could see nothing changed but THEIR rating changed... I just don't think they are trustworthy
