Welcome to AL WileECoyote! There's actually quite a few in Huntsville but only one or maybe 2 others post on here and not on a regular basis. I know of about 6 exiges in town and probably close to 12 Elises though I've only met a hand full of them since I've owned mine.
There's the North Alabama British Motoring Society (NABMS) that's up here in huntsville but i'm not sure about central AL. Nashville has a huge Cars & Coffee event. It's every weekend but the exotics come out on the first weekend of the month. A Bugatti Veyron and the last Jag xj220 were some of the cars to show up last month.
