Maybe it's something with Nissan dealerships. The experience buying my wife's Maxima was terrible, too. They kept us there for more than 4 hours - even with my children who were young at the time - and there was no trade-in involved. They tried every trick in the psychology playbook to squeeze every last penny they could out of us. I really loathe the way they make you wait to try to break your will. Bastids!
Good luck with the cRoutan. It's probably equal to the 5 in resale leprosy. I almost bought one of those before the 5, but I was reading about alignment issues with them at the time, and a host of other problems, and during my test drive I could have sworn it was pulling to the right. Placebo effect and all. Anyway, it was being offered at a deep discount as it had been on the lot there for almost a year!
