on the TV show,Extreme Homes,they showed a converted gas staion.It was built before the era of 'modern' filling stations. The guy did a great job of converting the upstairs to living quarters. The ground level still looked like a garage.
I did a search,but couldn't find it. I have it on VHS tape. He had a 40's Chevy tow truck sitting in the bay. He had someone blow up a picture of the truck sitting there,and put it on the garage door. it looked like the door was open when it wasn't.
He used tool cabinets for vanities and storage. There was a neon Mobil flying horse ion the bedroom wall. A lot of polished diamond plate,but very tasteful.
