My family has purchased here twice, now. Enormous selection but also killer warranties available to put your mind at ease with buying a used car. Just helped our son get a car he needs for work study in California at 2.9% financing and for less than $2k threw on a bumper to bumper warranty that will add another 110k miles with no deductible for repairs at Carmax or $50 if can't get to one. Includes rental coverage and towing. And zero haggling or sales pressure. What more can you ask for from a used car experience?
And it IS a USED CAR experience. Most of the negative reviews here seem to forget that. These guys will add warranties the manufacturers will not. They wouldn't offer them on cars they don't think are reliable, but these are used cars so get one and put our mind at ease. Also, all car dealer trade in scenarios undervalue your existing car compared to selling privately. That margin is how the dealer makes money. If you want that margin for yourself you're gonna have to give up the convenience of the trade-in and sell it yourself.
