If you're a fan of Porsche's GT3 series, you're going to want to own the Porsche 911 GT3 RS 4.0 ($185,000). Limited to just 600 vehicles worldwide, the latest — and last — GT3 RS sports Stuttgart's highest-displacement, most-powerful naturally aspirated flat-six engine ever, which turns its 4.0L into 500 hp, a 0 to 60 time of 3.8 seconds, a 0 to 124 mark of under 12 seconds, and a top track speed of 193 mph. Other features include the signature large rear wing, central twin tailpipe, an aerodynamically optimized body, a gleaming Carrara White paint job, and a weight of just 2,998 lbs — with a full fuel tank, of course.
It might not have been available for each of those 45 years, but it has been around since '67, so we'll give it the benefit of the doubt. The 2012 45th Anniversary Edition Chevrolet Camaro ($TBA) celebrates the birthday of Chevy's pony car by adding 11 horsepower to its V6 LFX engine and offering 20-inch dark silver wheels, dark silver trim for the fog lamps and taillight bezels, HID headlights and a rear spoiler standard, body-color roof molding, a jet black interior with red, white, and blue stitching on the seats, white gauges, a 45th Anniversary hood and desk stripes, and tons of badges — just in case you forget that you're driving the car equivalent of a birthday cake.
