I haven't bought a car that wasn't either a magazine (Japan used to have 300 page books) or an internet shopping experience first.
But, I'm also the kind of shopper that is looking for a specific make-model-trim. I have ended up buying a differentcar off the lot but that was only because I had used the internet to go check out what I thought I liked.
Yes, I have cruised a lot but that's window shopping for giggles because I was already at a dealer a few doors down.
Do people really just go to a dealership and say "HI! I"m looking for a car to buy, what do you have?" ?
