About the 1988 Porsche 928 GT

The 928 GT represents Porsche's final evolution of their grand touring flagship, arriving as the model's swan song with meaningful performance upgrades. Built from 1988-1992, the GT featured a more aggressive aero package, wider rear fenders, and crucially, a revised 5.0-liter V8 producing 326 horsepower, up from the standard 928's 288. The suspension received recalibration for sharper handling, while the interior gained sport seats and revised trim. Only around 2,000 GTs were produced globally, making it the rarest 928 variant. Originally priced at $74,000, these front-engine Porsches have found renewed appreciation among collectors who recognize the GT's unique position as both the ultimate 928 and Porsche's last attempt at a luxury GT before focusing entirely on the 911. Clean examples with documented maintenance are increasingly sought after, representing excellent value compared to contemporary 911 Turbos.
