528e
1982–1988
The economy model, with the low-revving 2.7L M20 'eta' six making 121 hp. Lots of torque, not much top end. It's the belt-driven engine, so check the timing belt history.

Buyer's Guide
1982–1988
The E28 is the 5 Series that set the pattern: a proper four-door with a big six, rear-drive, and a dashboard angled toward the driver. The M30 in the 533i and 535i is about as durable as a BMW engine gets, and the M5 more or less invented the fast sedan. Parts are still findable and the mechanicals are simple enough to learn on. The catch is rust and forty-year-old electrics, and clean ones are getting hard to find. Buy the body first. Almost everything else can be fixed.
Prices checked January 2026. Rough US market ranges. Location, history, and options move these a lot.
Rusty or non-running cars needing significant work. Common on East Coast and Midwest cars. Budget 2x purchase for restoration.
Running and driving with cosmetic flaws or deferred maintenance. Good starting point for an enjoyable classic.
Well-maintained 535i/535is examples with good history. Minor flaws acceptable at this level.
M5 models or exceptional 535is examples. Fully documented, low miles, original or properly restored.

Desirability
1983–1984
The first big-six car, with the 3.2L M30 making 181 hp. Replaced by the 535i after two years, and shares most of its parts.
Desirability
1985–1988
The one to buy: the 3.4L M30 with 182–208 hp, plenty of torque, and very little drama. The 'is' adds sport suspension and a limited-slip differential.
Desirability
1988 (US)
The original fast sedan, with the hand-assembled S38 3.5L six making 256 hp. BMW built 1,340 for North America, all sold as 1988 models, and values keep climbing.
Desirability
1985–1986
The M21 2.4L turbodiesel. Rare in North America, with a following of its own, but parts are harder to find.

What I'd check on any E28 before buying, with a rough cost if it's bad. Print it and take it with you.
