7993 is a cute midrange set that takes me back to the good ole Legoland Shell 6378 Shell Station from about 15-20 years ago (which was itself probably a reincarnation of 6375 Gas Station, which probably wasn't the first gas station either). Their designs are pretty similar, although 7993 has twice as many parts.
(Above: Good ole 6378, which is still at my parents' house somewhere in Kansas City)
All in all, a fun and somewhat inexpensive addition to the city. Stay tuned as Legomania continues...
