You're paying for that warranty though. If you really want one, you can buy one yourself from one of several competing aftermarket warranty companies.
Used car dealers suck, in every way. They add zero value other than having a selection of cars in one place, and possibly a selection of lenders for financing if you need that. They also know every trick in the book to get you to pay more for the car than it is really worth.
Best way if you have a little time to do research and watch the local market is to buy a car from a private seller.
The car websites will also clean/inspect the cars and ship the car to your house which is nice if the car you want is not near where you live
But yes generally my experience with https://clutch.ca was they push you to some expensive financing deal through their people.
