We found Maxon via TrueCar. Even with a firm out the door quote in hand, they resorted to high pressure tactics the entire time.
For 3 hours we had to argue with them to honor the deal. They threw everything in the book at us, "you have to finance", you have to get VIN etching, you have to take cargo nets", until they finally relented.
We got a good deal, but it was a huge hassle to deal with them. They are not honest or reliable in my opinion, and don't seem to care at all about their customers.
