The 928 S4 represents the final evolution of Porsche's ambitious grand tourer, produced from 1987-1991 as the most refined version of Stuttgart's front-engine flagship. Its naturally-aspirated 5.0-liter V8 delivered 316 horsepower through either a 5-speed manual or smooth 4-speed automatic, propelling this sophisticated GT to 60 mph in just 5.7 seconds. The S4 featured the distinctive 'Cup' design wheels, revised bodywork with integrated spoilers, and an interior that balanced luxury with Porsche's sporting DNA. Originally intended as the 911's successor, the 928 never quite captured purists' hearts, making clean examples increasingly sought-after today. The manual transmission cars, representing roughly 20% of S4 production, command particular attention from collectors who appreciate the 928's unique position as Porsche's only front-engine sports car. Values have steadily climbed as enthusiasts recognize the S4's exceptional build quality and timeless Tony Lapine styling.
