Shorts for the auction and a sweater for dinner and the Sun Valley Resort headliner show fits September in Sun Valley. The historic Wagon Days celebration with its full western theme of parades and activities rounds out hundreds of available venues. Sun Valley is where celebrity icons and celebrity cars are common enough that there is little distracting fanfare. Cars include vintage classics, classics, sports (US & Euro), exotics, luxury and muscle. An upscale, but casual collector car auction with celebrity flair in a setting only Sun Valley Resort can offer.
