The E38 succeeded the E32 generation and was produced from 1994 to 2001. It was offered in standard and long-wheelbase (L) body styles and positioned directly against the Mercedes S-Class and Lexus LS.
Engine options ranged from inline-six units to large V8s and a flagship V12, satisfying buyers from executive fleet managers to performance-oriented drivers. A 5-speed automatic transmission (ZF 5HP24) was standard across most variants. A facelift in 1998 brought revised front styling, updated interior materials, and revised equipment levels.

How to Check a Used BMW 7 Series E38's History
Before buying a used BMW 7 Series E38, it is essential to ensure full transparency about its past. Undisclosed accidents can hide poor-quality repairs that directly compromise the safety of the driver and passengers.
The E38 presents specific risks that are invisible to the naked eye. Given its age, a collision history may have resulted in improperly realigned front subframe mounting points, unreplaced side curtain airbag modules, or hastily repaired rear air suspension components that appear functional but fail without warning. Rust repairs hidden beneath fresh paintwork are also common on high-mileage examples that have spent years in northern states. It is therefore strongly recommended to check the vehicle's complete history using its license plate or VIN number before making any purchase decision.

Key Strengths
The BMW E38 earns its reputation as one of the best used luxury buys from the late 1990s for several reasons.
First, build quality was genuinely excellent for its era. Panel gaps, interior materials, and structural rigidity were class-leading — and well-preserved examples still feel solid decades later.
The inline-six 728i is particularly well regarded for its mechanical simplicity and long-term durability when properly maintained. Even the M62 V8 found in the 740i, once its known Nikasil issues are accounted for, is a strong and refined engine in later production cars.
Driving dynamics remain impressive. The E38 steers, rides, and handles with a precision that later 7 Series cars arguably lost. The suspension, while complex, delivers a genuinely satisfying balance between comfort and control.
Parts availability is good and improving as the classic car community embraces this generation. A strong enthusiast community means knowledge, DIY guides, and affordable used parts are widely accessible in the US market.
Known Reliability Issues
728i — M52 / M54
Coolant system failure is the most common issue on the inline-six variants. The plastic coolant expansion tank and thermostat housing become brittle with age and can crack without warning, causing rapid coolant loss. Severity: Critical. Typical appearance: 80,000–100,000 miles.
VANOS unit wear affects the variable valve timing system. Symptoms include rough idle, loss of power at low RPM, and rattling on cold starts. Severity: Moderate. Typical appearance: 80,000–120,000 miles.
Oil leaks from the valve cover gasket and oil separator are common and worsen with age. Left unaddressed, oil can contaminate the ignition system. Severity: Moderate. Typical appearance: 70,000+ miles.
730i / 735i — M60 / M62
Nikasil cylinder bore wear is the most notorious issue on early M60 engines (pre-1996). High-sulfur US fuel accelerated bore wear, leading to loss of compression and internal engine damage. Any M60-equipped car must be tested for compression before purchase. Severity: Critical. Typical appearance: 60,000–100,000 miles.
The M62 (post-facelift) resolved the Nikasil problem by switching to Alusil, but introduced a new concern: timing chain tensioner failure. Worn tensioners cause chain rattle on cold starts and can lead to timing chain jump if ignored. Severity: Critical. Typical appearance: 80,000–120,000 miles.
Water pump failure on M62 engines is common. The impeller is plastic and prone to cracking, reducing coolant flow and causing overheating. Severity: Critical. Typical appearance: 70,000–100,000 miles.
Head gasket seepage can occur on M60 engines with Nikasil damage or chronic overheating history. Always check for white smoke and milky oil. Severity: Critical. Typical appearance: varies.
740i / 740iL — M62
In addition to the timing chain and water pump issues shared with the 735i, the 740i in US trim has a known issue with the CCV (crankcase ventilation valve). A failing CCV creates excessive crankcase pressure, leading to oil leaks and rough running. Severity: Moderate. Typical appearance: 80,000–100,000 miles.
Throttle actuator (EML system) faults are also reported on V8 variants. The electronic throttle can malfunction, causing hesitation or limp mode. Severity: Moderate. Typical appearance: 80,000–120,000 miles.
750i / 750iL — M73
The M73 V12 is mechanically simpler than many V12 engines — no variable valve timing, relatively low stress — but its complexity doubles many jobs. Cooling system failures are common and expensive: two thermostats, two coolant circuits, and age-related hose deterioration all require attention. Severity: Critical. Typical appearance: 80,000–100,000 miles.
Fuel injector wear and fuel pump issues appear on high-mileage V12 cars. Symptoms include rough running, misfires, and hard starting. Severity: Moderate. Typical appearance: 100,000+ miles.
Labor costs on the 750i are significantly higher for any repair due to engine bay accessibility. Budget accordingly.
Chassis Issues
Front control arm bushings and ball joints wear predictably and affect steering feel and alignment. This is a known wear item on all E38 variants. Severity: Moderate. Typical appearance: 60,000–90,000 miles.
Rear air suspension (self-leveling) on equipped models is a frequent failure point. Air struts and the compressor degrade with age. Replacing the air system with a conventional coilover conversion is a popular and cost-effective solution. Severity: Moderate to Critical. Typical appearance: 80,000–120,000 miles.
Subframe bushings crack and deteriorate with age, causing handling imprecision and knocking noises over bumps. Severity: Moderate. Typical appearance: 80,000–120,000 miles.
Electronics and Software
The E38 introduced several advanced electronic systems that were cutting-edge for the 1990s — and are now aging accordingly.
Body control module (GM5) failures affect central locking, windows, and interior lighting. Symptoms include intermittent lock behavior or windows stopping mid-travel. Severity: Moderate. Typical appearance: age-related, most common on pre-facelift cars.
Instrument cluster pixel failure is extremely common. Individual display segments drop out, making the speedometer or odometer unreadable. This is a solder joint issue and can often be repaired. Severity: Minor to Moderate.
Xenon headlight control module failures cause flickering or non-functioning headlights. Replacement modules are available at reasonable cost. Severity: Moderate.
Maintenance and Servicing
The E38 is not a low-maintenance vehicle. Budgeting realistically for upkeep is essential before purchase.
Oil changes should be performed every 5,000–7,000 miles using quality synthetic oil meeting BMW LL-98 specifications. The extended 15,000-mile intervals suggested by the on-board service indicator are not appropriate for aging engines.
Coolant flushes should be performed every 3 years regardless of mileage, given the age-related brittleness of plastic cooling system components.
Spark plugs on the V8 and V12 engines should be replaced every 30,000 miles. Ignition coils on V8 variants are a wear item and often replaced as a set.
Transmission fluid in the ZF 5HP24 automatic should be changed every 50,000 miles — BMW's "lifetime fill" designation is not realistic on a 20+ year old vehicle.
Typical annual maintenance costs for a well-kept E38 range from $800 to $1,500 for routine items. Budget an additional $1,000–$3,000 in the first year of ownership for deferred maintenance catch-up, particularly on cooling system and suspension components.
Parts to Watch / Replace First
Coolant expansion tank — plastic tank cracks with age and should be proactively replaced on any E38 over 80,000 miles regardless of apparent condition.
Thermostat and housing — plastic housing is a known failure point; replace with an updated unit using an aluminum housing where available.
Water pump — especially critical on M62 V8 engines; the plastic impeller version must be replaced with an upgraded metal impeller unit.
Timing chain tensioners — critical on M62 variants; inspect and replace if rattle is present on cold start.
CCV valve and oil separator — replacement is inexpensive and prevents oil leaks and rough running on V8 cars.
Front control arm bushings — standard wear item; replace as a full kit including ball joints for best results.
Rear air struts or conversion kit — if the original air suspension is failing, a conversion to conventional springs is a reliable and cost-effective long-term fix.
Instrument cluster — pixel repair or replacement should be budgeted for any example with display issues.
GM5 body control module — have a spare on hand or source a tested used unit if electrical gremlins are present.
FAQ
Is the BMW 7 Series E38 reliable?
The E38 is mechanically sound when properly maintained, but it is not a forgiving car if maintenance has been neglected. The inline-six models are the most reliable overall, while V8 and V12 variants require more attention and budget. A well-maintained example with documented service history can be very dependable.
What is the best engine option in the E38?
For reliability and running costs, the 728i with the M54 engine (post-1999) is the strongest choice. For performance with manageable maintenance, the 740i M62 (post-1996, avoiding early Nikasil units) strikes the best balance. The V12 is best reserved for enthusiasts who understand its costs.
How many miles will a BMW E38 last?
A well-maintained E38 can reach 200,000+ miles. The inline-six and later V8 engines are long-lived if cooling system components are kept fresh and oil changes are performed on time. Neglected examples, however, can develop serious engine issues well before 150,000 miles.
Is the BMW E38 expensive to maintain?
Relative to its original segment, yes. Parts costs are reasonable given the car's age and enthusiast support, but labor can be significant — especially on V8 and V12 models where accessibility is limited. Plan for $1,000–$2,000 per year in maintenance on a driver-quality example.
Which E38 should I avoid?
Avoid any pre-1996 M60-engined car (730i) unless a compression test confirms the cylinders are healthy. Also avoid cars with failed rear air suspension that haven't been properly repaired or converted, and any example without a clear coolant system service history. High-mileage 750iL cars with no service records are high-risk purchases.
Does the E38 share any components with the BMW 5 Series E39?
Yes — the E38 and the BMW 5 Series E39 share several mechanical underpinnings, including the M52/M54 inline-six and M62 V8 engine families, as well as the ZF 5HP automatic transmission. Reliability patterns and common failure points overlap significantly between the two models.
Conclusion
The BMW 7 Series E38 earns a reliability score of 6.5/10 as a used buy. It is a genuinely rewarding car to own, with outstanding build quality for its era and a driving experience that remains engaging today. However, it demands proper maintenance and an honest budget. The inline-six 728i is the safest long-term bet, while the 740i offers the best performance-to-cost ratio. Choose a well-documented example, address the cooling system and suspension proactively, and the E38 will repay you with years of refined, characterful motoring.
