I recently applied for an auto loan through LendingTree. While I got a bunch of offers from different banks, none of them compared to the kinds of financing options available from dealers right now. I guess, if you're buying a car from another person or a mom-and-pop used car dealership instead of one of the major dealers, you could use LendingTree to get a competitive rate. But in this environment where dealers are giving away more and more incentives in the form of low APR financing, it just doesn't make sense to go with any other option.
