I have the "City Classics" service station. A bit expensive, but a VERY nice little kit. It is SIMPLE to assemble...in less then an hour. It comes with some nice little bits too. Your choice of 2 different style signs, 2 styles of gas pumps, a soda machine and a "bagged Ice" freezer, fuel island, and oil can racks. You could convert the solid bay doors into working ones pretty easily. I got a detailing kit from Walthers that added a floor lift, counter with cash register, "Free Air" pump, engine hoist, mechanics creeper, big "Snap-On" style rolling tool chest, another ice machine, benches, fuel island canopy, more oil can racks and trash cans. There are 2 different kits available..vintage 40s/50s or modern, so that a personal prefference. The silly part is that the detail kit was more then the building! $20 for the details, $13 for the garage. You can find them at most good train hobby shops. I shop at one nearby and always find scenery/detail items to use with my slot cars....traffic cones, trash dumpsters, forklift, pallets, junk, sheds, houses and stores, telephone poles, and street lights. When I can get this all in one layout, it's gonna look cool as can be! Now to just buy a house with a big enough basement or spare room...thats the REAL trick!!!!
