deceptively efficient, fast, and safe cars of all time. The fourth
major update, the S4, is all of that and more. - Modern Motor,
August 1989 With a top speed of 170 mph, ultimate autobahn cruiser
was an accolade frequently rendered in favor of the Porsche 928
over its four major iterations in the course of the model's 17-year
run (from 1978 launch through 1995). Partly with that grand touring
use in mind, the majority of 928 cars came equipped with automatic
transmissions. The S4, introduced in 1987, was the identification
for the fourth design iteration of the model, arguably the most
consequential. An updated 5-liter water-cooled V8 engine with new
pistons, a new cylinder head with more aggressive camshafts and
larger valves, and a 10.0:1 compression ratio produced 316
horsepower. This power news was accompanied by redesigned bodywork
in both the front (four fixed driving lights in addition to the
pop-up headlights) and rear of the car (a new fixed spoiler and
re-styled taillights) and ensured Porsche-o-philes could easily
identify the new model. Handling continued as a surprising 928
strength and was described as laser sharp by Road & Track at the
time. Although the 928 cars languished for many years in the
collector market, that lapse has ended with values showing
excellent appreciation over just the past few years. Offered here

white over burgundy. It has been primarily a southern car with
prior ownership in Florida and Missouri. Something of a driver's
928, it was ordered with limited-slip differential. Its complete

Porsche CD-2 Beginning with its burgundy leather interior, this 928
S4 shows beautifully overall, with one exception. Its dash has
suffered cracking and surface distortion, so there is a dash cover
in place. This should not be taken as a sign of mistreatment or
owner neglect as nearly all of the 924, 944, and 928
front-engine/transaxle Porsches of the eighties suffered a similar
fate. The cause was a sandwiched material used by the factory that
did not stand up at all well to sunlight over time. Unfortunately,
by the time the deterioration was noticed, it was too late for even
the most fastidious owner to effectively mitigate. As the remainder
of this car's interior demonstrates, virtually all other surfaces
were up to Porsche's traditional high standards, and kept that way
by the car's owners over the years. The burgundy leather is in
excellent condition with no rips or tears, door trim is complete
and undamaged, instrumentation and center-console switchgear is
unmarred, and even the carpeting beneath the rear hatch-glass is
un-faded. The headliner is free of sagging and the factory sunroof
operates as intended. A later-model Alpine audio head unit replaces
the factory-supplied Alpine unit. Rear-seat passengers are treated
to a separate air-conditioning supply. Grand Prix white is so
valued by collectors in part because the color allows the other vis
