Anyone making a personal Top-10 Porsches list would surely have to include the 1973 911 Carrera RS 2.7 and 1974 911 Carrera RS 3.0. There’s a much bigger difference between the two than their 0.3-liter cylinder displacement. The RS 2.7 was rare, with just 1,580 made and the car not sold in the U.S. market. In comparison, the RS 3.0 was a unicorn, a homologation special for the 3.0 RSR with just 55 made. That explains the $1.6M-$1.8M pre-sale estimate at RM Sotheby’s Monterey auction in August for what many consider the best RS 3.0 extant. A car with factory provenance, it remains in original condition with just about 18,000 miles.
