On July 26, London auction house Bonhams is staging a sale of Porsche and Lotus motorcars at the Silverstone Classic, one of the UK's premiere motor sport events. Unlike some auctions, the Silverstone sale skews to the more affordable side, without any million-dollar motorcars. In fact, most lots are priced below $100,000, yet there are several beautiful examples of highly collectible classics and contemporaries from the two famous marques.

For instance, the gorgeous 1959 Porsche 356B coupe pictured here, which is estimated at only $36,000 - $40,000 and is in impeccable condition. Also on offer: a legendary 1973 Porsche 911 Carrera RS touring coupé, est. $220,000 - $260,000; a 1972 Porsche 911 3.0-litre rally car, est. $80,000 - $100,000; a 2007 Lotus Exige Cup 255 coupé, est. $90,000 - $110,000; a 1967 Porsche 911 2-litre coupe, est. $64,000 - $72,000; and a 1973/2006 Lotus Elan +2 Spyder Zetec coupe, est. $40,000 - $50,000.
