Set to hit the RM Sotheby’s auction block later next month is this super rare 1993 Porsche 911 RSR. One of only 51 models ever made, this race-ready classic features a host of performance upgrades, although it hasn’t been driven in 24 years and only has a lowly six miles clocked on its odometer. Sporting a Polar Silver Metallic paint job, the car combines the wide body of a 911 Turbo with a 3.8-liter flat six-cylinder engine capable of spitting out 350 horses — good for 0 to 60 mph in 3.7 seconds. On par with its power and stylistic exterior is a done-up interior cabin sporting a vibrant red color scheme. With design, performance and rarity all working in the Porsche‘s favor, RM Sotheby’s estimates the car can fetch a price tag of up to $2.4 million USD.
