The story
An evolution, not a revolution, and that was the point.
The E28 looked a lot like the E12 it replaced, but underneath BMW reworked nearly everything: a new rear suspension, a dashboard canted toward the driver, and the first use of BMW’s Check Control warning panel in the 5 Series.
In the US it arrived as the economical 528e, followed by the 533i and, from 1985, the 3.4-liter 535i. The 535is added sport seats and spoilers. At the top sat the M5: a hand-assembled sedan with the twin-cam six descended from the M1 supercar.
Today the E28 is the classic 5 Series that’s easiest to live with. It’s simple, durable when sorted, and still affordable outside the M5.

Why buy one
Pros
- The M30 "big six" is famously durable, with huge parts and community support.
- Thin pillars and a tall glasshouse: some of the best visibility of any 80s car.
- Manual gearboxes were widely available, and swaps are well documented.
- Simple, analog and easy to wrench on at home.
- Non-M cars are still within reach of a normal budget.
Think twice
Cons
- Rust is the number-one killer, and it hides in places that are hard to inspect.
- The 528e's eta engine trades power for economy and feels slow today.
- Many US 535is were automatics, so good manual cars carry a premium.
- The original R12 air conditioning is weak, and retrofits add cost.
- M5 engine work (S38) is specialist and expensive.
Buyer's guide
What to check before you buy
Body
Rear wheel arches, jacking points, sunroof drains, the battery tray, and under the front and rear valances. Lift the carpets.
Engine
Cooling-system history is critical. M30 heads can crack after overheating. Look for coolant in the oil and listen for a ticking valvetrain.
Chassis
Worn front thrust-rod bushings cause a shimmy under braking. Check the rear subframe mounts and the ABS on later cars.
Electrics
Check that the Check Control panel, onboard computer, power windows and gauge cluster all work. Ground faults are common.

Where values sit
Non-M cars cluster around $10k–$20k, and clean manual 535i and 535is cars sit at the top of that range. The M5 lives in a different world. Good US cars trade around $50k, exceptional ones have reached six figures, and a 9,800-mile example set a record near $200k in 2026.

The verdict
Buy the best manual 535i or 535is you can find, and spend the savings on rust prevention. Buy the M5 only if you're buying history.
