In just a bit over a week. You don't wanna miss it, it's the last one until next spring. Plus, there's always something good. Last time, there was a Huayra, Enzo, CLA AMG, and an F1...all at once. Since it seems like way more Opponauts ended up going last time than I expected, feel free to email me at email@example.com to meet up. It's obviously understandable if anyone doesn't want to meet up, but I just figured some people may want to put a face/car to the username.
Seriously, you should come. Usually there's at least one special showpiece (last time, the Huayra-The rest just kind of showed up), but since I don't know what that is yet, I'm just going to pretend it's something incredible and say you should definitely come.
