The 1981–1987 BMW 525i Sedan is part of the E28 5-Series, a second-generation mid-size executive car praised for its build quality and driver-focused handling. As a core model of the E28 line, the 525i was noted for its balance of performance and reliability, often ranked well among its 80s contemporaries for speed. The E28 is famous among enthusiasts for updating the brand's classic shark-nose design and for offering a rewarding driving experience, particularly when suspension components are refreshed. While the E12 (the predecessor) was infamous for poor rust resistance, the E28 improved this. Today, the 525i is a sought-after classic for daily driving or weekend enjoyment, appreciated for its analog feel and ease of maintenance.
Common reliability issues for the BMW 525i include oil leaks from the lower engine area, front tension strut bushing failure, and issues with the blower fan resistor and cooling system (coolant loss). Maintenance may involve addressing these typical issues as the vehicle ages.
