The flagship. Exceptional when maintained, expensive when not. The used 7 Series market in Southern California is full of examples that were serviced at dealerships until the warranty expired — then handed off to owners who didn't fully understand what they'd taken on. Know what you're getting into.
The E65 (2002–2008) was the most technologically ambitious BMW of its era and is now deeply depreciated. The F01 (2009–2015) refined the formula and is the most common used 7 Series in Ventura County driveways. The G11 (2016–present) is early in its depreciation curve.
Most 7 Series models use air suspension as standard or optional equipment. Air struts, compressors, and ride height sensors all fail with age. A 7 Series that sits lower than normal overnight has a leak somewhere in the air suspension circuit. Replacement air struts run $400–$900 each; compressors add to the total. Southern California's stop-and-go driving keeps the compressor cycling more than highway use would, accelerating wear.
The N62 naturally aspirated V8 in E65 745i models burns oil through degraded valve stem seals — particularly on cars that sit or are driven infrequently. Blue smoke on startup is the symptom. Valve stem seal replacement is a significant labor operation. An E65 745i is inexpensive to buy because ownership costs are real. Budget accordingly.
The N63 4.4L twin-turbo V8 in F01 750i models prompted BMW's Customer Care Package program — an acknowledgment that oil consumption, valve stem seals, high-pressure fuel pumps, and cooling system components were failing at rates that warranted goodwill coverage. Any F01 750i purchase should confirm whether the CCP was completed in full. An N63 that hasn't had CCP work is carrying deferred time-sensitive repairs.
7 Series models are BMW's technology showcase. That means more electronics to fail. iDrive controller failures, adaptive headlight motor failures, active roll stabilization faults, parking sensor failures, and comfort access glitches are all reported across generations. These rarely strand you — but they affect the ownership experience and can be expensive to diagnose and repair without BMW-capable diagnostic equipment.
V8-powered 7 Series models generate substantial heat. Both N62 and N63 engines have documented cooling system vulnerabilities — water pumps, thermostats, expansion tanks, and turbo coolant lines on the N63. A 7 Series with an uncertain cooling system history is a liability. Simi Valley summer temperatures leave no margin for a marginal cooling system.
There is one non-negotiable rule for buying a used BMW 7 Series: complete, verifiable service records. A 7 Series with documented dealer or independent shop history — oil changes at correct intervals, cooling system service, CCP completion on N63 models — is a reasonable ownership proposition. A 7 Series with a vague or missing service history, regardless of how clean it looks, is a significant financial risk. The repair costs the previous owner avoided will become yours.
More so than any other BMW, the 7 Series warrants a professional pre-purchase inspection before purchase. A two-hour inspection by a BMW-experienced technician with proper diagnostic equipment can surface deferred maintenance, active fault codes, and air suspension condition that a test drive will never reveal.
Budget $2,000–$4,000 annually for a used 7 Series in Simi Valley — more for an E65 or an F01 750i without CCP history. This isn't speculation; it reflects what attentive owners spend keeping a flagship BMW in proper condition.
