Did an online trade-in and purchase, but had to come in because we couldn't get PayPal deposit to work. Guess what? Couldn't honor online pricing for trade (quote was ridiculously high). That's ok, we negotiated. Time to pay and then they state price is only if we finance (we said online we were paying cash). That wasn't anywhere online and I'm looking at a $4k bogey on this deal. I walked. They get 2 stars for being courteous, otherwise 1 for honoring a written deal.
