2000 · BMW7 Series 740i/740i Sport
What the data shows
At 135,000 miles, this E38 740i Sport remains a desirable, comfortable V8 sedan, but timing-chain guide failure and brittle cooling plastics are the consequential concerns. Documented service work, including the alternator, ignition parts, and window regulator, helps.
Budget about $13,000 near term, verify cold-start chain noise and coolant history, and the asking price is at or below market.
At a Glance
What this guide surfaced$4,400 is about 32% below the $6,500 market estimate, so condition and history need close checking
guide breakage at this mileage can damage the engine and requires invasive repair
a cracked radiator or expansion tank can dump coolant quickly and overheat the V8
the stated low refrigerant condition needs leak testing rather than a simple recharge assumption

Detailed findings, 12 items
Click any card for the full breakdown, repair cost, and what to check. Items already handled by the owner show as checked.
Reflects the open findings; items the owner handled are excluded.
Confirm these before you buy. If you or a mechanic can verify them, that clears the car instead of ruling it out.
Timing-Chain Guide Failure
The M62 timing-chain guides fracture and shed plastic, producing cold-start rattle before slack lets the chain jump timing. Continued operation can bend valves or destroy the engine, and replacement requires extensive front-engine disassembly.
Radiator Plastic Tank Cracking
The radiator's plastic side tanks and neck become brittle and crack, releasing coolant around the radiator edges or hose connections. A sudden coolant loss can overheat the M62 and leave the car stranded.
Costly repairs, but not urgent to verify before you buy. Price them out and use them to negotiate.
Expansion Tank Cracking
The coolant expansion tank develops age-related cracks around its seams and hose ports, leaving white residue or a low-coolant warning. The leak lowers system pressure and can progress to overheating during traffic or highway driving.
5-Speed Transmission Valve Wear
The 5-speed automatic transmission develops valve-body and sealing-sleeve wear, causing delayed engagement, flare shifts, or harsh shifts once the fluid is warm. Continued slip raises clutch wear and can turn a hydraulic fault into a transmission rebuild.
Front Thrust-Arm Bushing Wear
The front thrust-arm bushings soften and crack, producing steering shimmy under braking and a loose or wandering feel over uneven pavement. Continued wear increases tire cupping and makes the large 18-inch wheels more sensitive to road impacts.
Valley Pan Gasket Leak
The valley-pan gasket at the rear of the M62 intake valley hardens and leaks coolant into the engine valley, often leaving no obvious external puddle. The trapped coolant can create a sweet smell and eventually lower the expansion-tank level.
Crankcase Ventilation Diaphragm Failure
The rear crankcase-ventilation diaphragm and hoses harden or tear, creating a vacuum leak that produces rough idle, whistling, and increased oil consumption. The unmetered air also disturbs fuel trims and can trigger engine-management faults.
Minor wear typical for the car’s age. Not worth negotiating over, but good to track as an owner.
Engine Mount Collapse
The hydraulic engine mounts collapse and allow the M62 to sit lower, causing excess vibration through the cabin and movement during throttle changes. The movement stresses nearby exhaust and drivetrain components while making idle vibration more noticeable.
Cluster Pixel Display Failure
The instrument cluster and information display lose pixels, leaving mileage, warning text, or radio and climate information partially unreadable. Heat and age weaken the display ribbon connections rather than the underlying vehicle systems.
Climate Control Module Failure
The automatic climate-control panel develops failed pixels and blower-control faults, leaving temperature settings unreadable or airflow stuck at one speed. The stated need to recharge the A/C is separate and should be leak-tested before refrigerant is added.
Valve Cover Gasket Seepage
The M62 valve-cover gaskets harden and seep oil down the cylinder-head edges, leaving oily residue and sometimes an oil smell on the exhaust side. The leak usually develops gradually but can contaminate ignition components if it reaches the plug wells.
Power Window Regulator Failure
What's working well
Engine Bay Cover Finish Peeling
The visible right engine-cover finish is peeling, exposing an aged cosmetic coating without showing a wet fluid leak in the buyer's inspection. The defect does not affect engine operation unless loose coating reaches moving or hot components.
This is cosmetic rather than mechanical, and the visible engine bay does not show an obvious active leak.
Mileage Display Matches Listing
The instrument cluster displays 135,454 miles, closely matching the stated 135,000-mile listing mileage. The buyer's inspection also shows no warning indicators illuminated in the photographed cluster.
The close agreement supports the mileage description and gives the buyer a consistent starting point for evaluating age-related service needs.
Every finding still open carries a question worth asking. Copy them as one message, already ordered by severity. Anything you have marked above drops off on its own.

Price & negotiation
BetaBased on comparable listings and the repairs you can document. A starting point for what this car should cost.
Discounts this deep are sometimes real, but they are also the classic pattern for scam listings, undisclosed damage, and title problems. Before paying anything: see the title in hand, check the VIN matches the car and the paperwork, and walk away from any seller who won't meet in person or asks for a deposit up front.
Price breakdown
Pricing models disagreed on this vehicle, so treat the market estimate as a rough range rather than a precise number. Recent local listings are the best tiebreaker.

Watch later
Lower-confidence or no-cost items to monitor.
Each range is what that one item costs if it turns out to be present. Not every item will apply to this car, so they do not add up to a bill. Verify with a mechanic.
Asking is $4,400 against a typical $6,500 for this car and mileage. The work is the difference, not the sticker.
Negotiate your offer
Asking is about 32% below the market estimate, so there may be less room to move. The documented repairs below are still relevant to raise.
- Documented critical/major repairs of $7,150–$18,750 you can point to.
- Strongest items to raise first: Timing-Chain Guide Failure, 5-Speed Transmission Valve Wear.
Pricing is in beta. The market estimate comes from research models and can be off by thousands on the same car, so check recent local listings before you rely on it. This is information to help you research, not a professional inspection, an appraisal, or financial advice.

In-person inspection
12 things to check before you buy
5 major and 5 caution findings, turned into a walkthrough for the driveway. Try it on this sample.
Before you leave: Ask the seller not to start or move the car before you arrive. A sales-ready car has usually been warmed up, and a warm engine hides the startup smoke, rattles and rough idle that the first section is built around.
01Cold Start CheckFirst1
Start the engine cold while you watch the exhaust and listen. Note how quickly it catches, the tint of any smoke, rattles in the first few seconds, and how smoothly it settles into idle. This is the one test you cannot repeat on the spot.
02Interior & Electronics3
Turn the key to accessory and then on, before starting. Confirm every warning light comes on and then clears, and test the windows, locks, climate fan, infotainment, and seats while the engine is off. Smell for damp, lift the mats to feel for wet carpet, and compare pedal rubber wear against the odometer.
03Engine & Systems6
Before the first start: pull the oil dipstick and look for a milky film, check the coolant for oil or rust, squeeze the radiator hoses for hard or mushy spots, and note the battery date. Once warm: confirm the cooling fans cycle, listen for belt noise, look for fresh seepage that was not there cold, and check that the A/C blows cold.
04Test Drive2
Drive a route with stops, a hill, and some open road. Feel for shift quality, clutch or torque-converter behaviour, brakes that pull or pulse, steering play, and any noise that changes with speed or steering angle.
Everything on this list is what you can see standing next to the car. A shop on a lift sees the rest, and a written pre-purchase inspection listing parts and labor is what a seller has to answer to. Budget roughly $100 to $150 at an ASE-certified shop.
