If i was building an office, I'd consider having a space to park a vehicle I love in the office. I would want it in a separate garage bay, but have a glass wall, so the vehicle could be clearly seen from my office. The reason for the separate bay is to keep the odors associated with many antique vehicles out of the office. Having the car there would be a potential conversation piece and it would be close at hand so it could be taken to go pick-up lunch. Of course, the garage space could be used as a place to hang out. If it is large enough, other garage related collectibles, such as motorcycles, bicycles, boats, signs, gas pumps, sports equipment, etc. could be displayed as well.

I would be a bit concerned about having a glass wall on the exterior of the building for security reasons. A glass wall inside a building should be OK.
