Here are my entries into this wonderful thread.
I don’t currently have a layout (everything is packed away) just a table by the dining room that I display items on and look at plans of plastic airplane model kits that I plan on building (eventually). 
Modeling trains is sometimes about memories and that will be the case with me. My next foray is to have a New York City section in the 1970’s and the 1980’s (from my youth) and South Florida section from the 1990’s to the present (my adulthood) so I’m purchasing and stocking up of items as I come across them.
Misplaced my O Gauge roads so the vehicles resting on cork will have to do, utilizing an MTH Tri-Rail Control Cab Car as a wonderful backdrop.
Just purchased three South Florida law enforcement vehicles. Next one to get is the Florida Highway Patrol Crown Vic with operating lights. Also plan on purchasing some NYPD squad cars, especially the one’s from the 1970’s colors if possible, like the Plymouth Fury shown in the attached photo from the Pelham One Two Three movie. 
I aim to get all vehicles in 1:43 to keep things to the same scale. Unfortunately, some items only come in other scales, but those will have to do like the 1:50 Greyhound Bus.
There will of course be some vehicles that the manufacturer says are 1:43 but are anything but such as the Orange Ford Focus that I’ve had for a few years. It is way too large compared to the other vehicles. The Beetle Bailey 1/32 Willys Jeep is there because… it’s Beetle Bailey! 
My favorites in my inventory are the 1:43 GM Fishbowl buses with the New York Transit Authority colors from the late 1960’s through the 1970’s with the "Bat Wing" advertising roof panels. I’m glad that Iconic Replicas offered these models so that I don’t have to wait for the rare (and thus ridiculously overpriced) Corgi 1:50 ones produced a decade ago to show up on auction sites.
