I'm not sure if Spur Cola is still in production or not, the best I can say is that it's not available here in Indiana. I found ads from the 80's, so there's a chance that somewhere out there someone is chugging a cold Spur right now. Really can't be sure!
There were a lot of different versions of this ad, all with different models proclaiming they'd never tasted a cola so fine as Spur. Nothing too exciting, though. I guess you have to leave it to Coca-Cola if you want big, flashy soda ads.
