Bruette posted info on a bunch of new Lionel HO stuff and this one definitely caught my eye! What a great building.
Apparently you can buy it pre-assembled or a kit. I'm imagining what a great starting point the kit would be for a super detailed structure. Look at all the glass! You could build the office in there and have it easily visible. Also, you could model a couple of the doors in the open position and put some cars inside. Put a few more in the parking lot and you'd have a real nice scene to catch people's eyes.
You could get as detailed as you want, tires, grease rack, oil can displays, old posters. The list goes on and on. The result would be impressive.
