Here's one of the reasons I chose Clark. Here is the Clark station compared to a Texaco station.
Not only are the Clark repairs complete, you can see the progress I've made when I haven't been working on oil cans. My sources gave differing accounts of the floor surface (I'm sure every station wasn't IDENTICAL). I chose the black and white diamond pattern to liven up the place. The showroom glass is plexiglas with plastruct bracing. When I measured the Clark station near my home, I was glared at by the owners of a taco stand who had taken over the lot. (the building was in the process of being sold). They had no legal claim to the building, so I measured it, and took pictures anyway. I don't know how long the building will be there, so I got my numbers while I could.
The Texaco station was started years ago. There was a Texaco station that had been modified to a used car lot a few miles from my home. The building had all the exterior panels intact. I was able to produce accurate drawings as I spent a day measuring everything to the amusement of the owners. The bathrooms were unchanged from the Texaco days, all materials and colors were intact and unaltered. I took quite a few pictures of everything inside and outside. Who knows, someday I may finish it, but it has rather a large footprint for the room I have.
I've also drawn up a Phillip's 66 station (also a large model footprint, even larger than the Texaco), but I haven't been granted permission to photograph the structure inside. Hopefully I can get that done before it's gone. There was a cool Shell station, too, but I waited too long on that one, it's gone.
Both structures are 1/25 scale.
