Engine & Transmission:
At the core of this build is a Metric Mechanic 4.0-liter in-line six that started life as an M30 engine, a truly special powerplant that defines the car’s personality. This engine was sourced new in a crate from a fellow enthusiast and paired with Extrudabody individual throttle bodies (ITBs). Engine management is handled by a Megasquirt ECU, with a base tune completed by Kassel Performance. The car will benefit from final tuning to fully unlock the engine’s potential. To help keep this special engine cool, a custom oil cooler was fabricated. This 528e also sports a custom exhaust that gives the car the appropriate soundtrack for those Sunday morning drives.

Exterior & Interior: 
Finished in Baltic Blue, this 528e presents with a confident yet understated road presence. The build intentionally began with a slick-top (non-sunroof) 1982 528e chassis, a highly desirable configuration. During the restoration, minor damage to the driver’s rear quarter was properly repaired. The vehicle was then placed on a rotisserie, allowing every inch of the chassis and body to be addressed correctly. More recently, the trunk lid and fuel door were resprayed due to a scratch on the trunk lid and the replacement of the fuel door. During the paint process, the car was upgraded with OEM BMW Euro front and rear bumpers, grilles, headlights, taillights, and headlight wiper mechanisms. (Note: headlight wiper arms and the correct reservoir are not currently installed.) All glass is in good condition and remains period-correct with factory markings. The exterior is completed with 17-inch forged ACT wheels (three center caps included), giving the car an OEM plus aesthetic with subtle motorsport influence.

Interior Material: Leather
The interior is a standout feature and a genuine time capsule, blending originality with rare new old stock components. Finished in OEM BMW black leather, the cabin reflects the high standards of this build. The rare manual sport front seats and rear seats were professionally recovered by Gary Macher of Newtown, Pennsylvania, a highly respected craftsman whose work appeared at Pebble Beach and other concours-level events. The car is also equipped with a refinished period-correct MOMO wheel with a rare Hartge center. Additional highlights include: • New old stock dashboard • New old stock Euro headlight switch • Additional NOS trim and switches where appropriate The original carpets remain in excellent condition for their age. Heating and air conditioning are fully functional, making the car enjoyable in real-world driving conditions. Overall, the interior delivers a refined blend of authenticity, craftsmanship, and usability that gives this E28 real character.

Model History: The BMW E28 5 Series, produced from 1981-1988, represented BMW's definitive executive sedan of the 1980s, with the 528e serving as the efficiency-focused variant powered by the innovative M20 "eta" engine. Introduced in 1982, the 528e featured BMW's fuel-efficient 2.7-liter inline-six that prioritized torque and economy over peak power, achieving remarkable fuel efficiency while maintaining the marque's driving dynamics. This model bridged BMW's transition from the angular E12 to the more aerodynamic design language that would define the brand through the decade. The E28's significance lies in its perfect balance of traditional BMW engineering with modern refinement, featuring improved aerodynamics, advanced suspension geometry, and the introduction of key technologies like ABS and on-board diagnostics. Against contemporaries like the Mercedes W124 and Audi 100, the E28 distinguished itself through superior handling dynamics and driver engagement. The 528e's M20 engine, while initially criticized for modest power output, has proven exceptionally durable and modification-friendly, making these cars increasingly sought after by enthusiasts who appreciate their robust M30-derived bottom end and potential for significant power increases through engine swaps and forced induction.
