1992 BMW M5: Buy or Avoid?
The 1992 BMW M5 is a legendary performance machine, but it demands a specific type of owner: one with deep pockets, mechanical aptitude, and a genuine passion for its analog driving experience. This is not a car for the faint of heart or the budget-conscious; its age, complexity, and specialized parts translate directly into significant ongoing maintenance and repair costs, making it a high-risk proposition for most. Prepare for an ownership journey filled with both immense driving satisfaction and substantial financial investment.
The 1992 BMW M5 is a masterpiece of automotive engineering for its time, offering an unparalleled driving experience for an executive sedan. However, acquiring and maintaining one is a serious financial undertaking that requires a significant initial investment for corrective maintenance and a substantial ongoing bu…
Best Model Years
1991-1993 (US-spec S38B36 models). Seek out cars with extensive service history, particularly for rod bearings and suspension. Euro-spec S38B38 (3.8L) models are also highly sought after but even more complex to maintain in the US.

Biggest Strengths
- Exceptional build quality for its era
- Robust S38B36 engine (when properly maintained)
