Vehicles on layouts: How much is enough?

I would like a 69 Camaro on my layout but too new although I might bend the "rules". I do have a Studebaker Hawk, though.  Has anyone ever set up a "car show" on Main St. ??  You could have anything you wanted to show and lots of cars.  I have several early jeeps, too, but also a Marx tin plate Army barracks in town.

During the annual pumpkin harvest, at the patch near the main line, quite few cars tend to gather in the parking lot.

Looks like a nice cheerful, friendly place to visit, just like our layouts themselves can be. I imagine many of us have visited real-life places like that. There is one in Upstate NY just outside of Homer and Tully, called Anderson's Market (but it has a building which fits the whole picturesque feel). You sure added interest to that stretch of track! Very nice.
