The original 987 Cayman marked Porsche's bold return to mid-engine excellence after the 914's mixed reception. Launched in 2005, this perfectly balanced coupe paired the Boxster's proven platform with a fixed roof and 2.7-liter flat-six producing 245 horsepower. What made the base Cayman special wasn't just its sublime handling—courtesy of that mid-mounted engine and 50/50 weight distribution—but Porsche's deliberate restraint in keeping it positioned below the 911. The result was pure driving nirvana at a more accessible price point. With its clean Pinky Lai-influenced design, precise steering, and that intoxicating flat-six soundtrack, the 987 Cayman has emerged as a modern classic. Values have steadily climbed as collectors recognize it as perhaps the last analog Porsche sports car, with manual transmission cars commanding particular premiums. The base model's lighter weight and purity make it increasingly desirable over its more powerful siblings.
