I think it's pretty nice that there are all these stores I can drive to where I can sell and buy a car in couple hours. That's risky buisiness-wise and most manufactures enjoy not taking that on directly. There are no haggle dealerships out there, you might like those more, and if the car you are interested in is low demand you should get a decent price there for one. Might be worth the less stress to you, won't make much of a difference month to month.
I'm no particular fan of the car buying experience although if you can take both financing and trade-in totally out of the equation--and have done your research--it gets a lot easier. You're also right that there are no haggle dealers and brands. When I bought one of my current vehicles (about 15 years ago now!) I test drove a couple different variants and the purchase process probably took less than an hour at a no haggle dealer that was selling the car at just about dealer cost according to Consumer Reports.
