Cars crave the limelight, as evidenced by their glossy exteriors and tendency to honk a-cappella power ballads when deprived of attention. Lavish love on prima donna machines with today's Groupon: for $15, you get two general-admission weekend passes to the 2011 Calgary Premier Collector Car Auction, presented by EG Auctions (a $30 value). The auction runs from Friday, June 10 through Sunday, June 12 at the Grey Eagle Casino.

One of Canada's largest collector-car auction companies, EG Auctions gathers a massive gallery of sleek vintage cars available for perusal and purchase. Auction guests scrutinize historic rides such as a 1970 Dodge Challenger, 1974 Jaguar, 1967 Shelby GT Fastback, and a fully restored 1916 steam-powered horse. Bidders vie for the affection of their chosen vehicles or place bets to woo an assortment of automotive memorabilia, ranging from a 2011 Crosley jukebox to authentic 1930s gas pumps. Assuage eyeball appetites at the Show and Shine event on Saturday at 10 a.m. and observe freshly polished autos of all astrological signs at their most glittery.
