1/18th dealership display

Update: Haha this doesn't surprise me that I did this but umm well, new walls are going up. Yea, its getting rebuilt. I got the window material this passed weekend and I decided that the mini Autosport just wasn't done well enough for my tastes. I got some new materials, walls are being rebuilt right now, so pictures will go up once they are done. Didn't like the simple box shape of the dealership. Going with a more "Hexagonal" look and arches. Little more complicated but this time its measure twice cut once so it takes longer but the end result will be much cleaner and pleasing to the eye.
Differences being made:
Outside:
-Walls being reshaped
-New finishes, stucko look on part and siding on non stucko'd walls
-Garden area/grass gravel pits to fill up space

Inside:
-Shiny white flooring
-Wall colors, any ideas?
-Cleaner corners, small details(pictures, etc.)

Going with a classier look so any ideas are great.
