Commonly reported ownership points, not a guarantee of faults. Always get an independent inspection.
The early super-saloon recipe.
The E28 M5 uses the M88/3 straight-six in a four-door 5 Series body. It is an early example of the engine-and-practicality combination that defines the M5 family.
The roots of the M5 idea.
A classic saloon needs a body and mechanical inspection together.
M88/3 is also represented here in the M635CSi coupé.
M88/3 · Inline-six
The first M5 adapts the M1-derived, 3,453 cm³ six-cylinder to a four-door sedan. The European M88/3 uses natural aspiration and a four-valve cylinder head.

Natural aspiration
Intake air enters without a turbocharger. Engine breathing, valve timing and engine speed shape the way torque builds.
Rear-wheel drive
A five-speed manual gearbox and rear-wheel drive complete the original M5 formula. The North American S38-powered model has a different factory output.
