What should I check when buying a used BMW 7 Series?

On a 7 Series, check cooling system records; oil leaks; cold-start test, on top of the checks for any used car: the body, tyres and engine, a test drive, and the paperwork for money owing, a write-off and the odometer.

How much is a used BMW 7 Series?

Most 2016 7 Series are advertised at $15,000 to $47,000, with 90,000 to 170,000 km on the odometer. Prices depend on the year, the kilometres, the badge and the condition.

Used BMW 7 Series Buying Checklist: What to Check

Before you go

0 of 5

What a 2016 7 Series is advertised for

Asking price: $15k to $47k
Odometer: 90k to 170k km

Asking prices, not sale prices: the middle 60% of the 53 advertised in the last 12 months, one listing per car.

Get the rego or VIN From the ad or the seller. Enter it at the top of this page: the make, model and year should match the ad.
Compare the price With what similar cars are advertised for.
Ask the seller How long they have owned it, why they are selling, any accidents and any money owing.
Ask for the service book And for the engine to be cold when you arrive.
Meet in daylight In dry weather. For a private sale, at the seller's home: the address should match the registration papers.

Inspection

0 of 17

Panels and paint Uneven gaps, paint that does not quite match and overspray on rubber seals point to accident repairs.
Rust Under the doors, around the wheel arches and under the boot floor.
Tyres At least 1.5 mm of tread, even wear across each tyre, and a spare.
Glass and lights No chips or cracks in the windscreen, and every light works.
Oil and coolant Check them cold. Milky oil under the filler cap, or oil in the coolant, can mean a head gasket fault.
Cold start Watch the exhaust and listen for rattles in the first few seconds.
Wear inside The pedals, steering wheel and driver's seat should fit the odometer reading.
Warning lights and controls Lights come on with the ignition and go out once the engine runs. Try the air conditioning, windows, locks and screen.
Flood signs A damp smell, water marks or silt under the carpets.

What to check on a 7 Series

Cooling system records Ask for receipts showing expansion tank, water pump, and thermostat replacement. No records means budget for an immediate overhaul.
Oil leaks Inspect under both valve covers and beneath the engine. Fresh or dried oil demands investigation before purchase.
Cold-start test Any stumble, rough idle, or hesitation should be scanned for fault codes across both DME banks.
Instrument cluster Check for dead or fading pixels in the speedometer and OBC display.
Central locking and windows Operate every window and the locking system from all positions.
Rear suspension With the engine warmed, check the rear sits at correct height and does not slowly settle after the engine starts.
Service history A V12 without comprehensive documented history is a high-risk purchase. Deferred maintenance compounds quickly on this platform.
Parts and workshop access Confirm a local specialist can source parts for the L7's extended body before committing.

Test drive

0 of 5

20 minutes or more On slow streets and at highway speed.
Steering and brakes It runs straight with your hands light on the wheel, and stops straight without shudder or squeal.
Gear changes Smooth, with no slipping or flaring revs. In a manual, a clutch that bites near the top of the pedal may be worn.
Noises Knocks over bumps, and whines or hums that rise with speed.
Temperature and leaks The gauge settles and stays put. After the drive, look under the car for fresh drips.

Paperwork

0 of 7

Money owing A car with finance owing on it can be repossessed after you have paid for it. A PPSR check shows it.
Write-off A statutory write-off can never be registered again, and a repairable write-off needs an inspection first.
Odometer Compare the reading with earlier records of the car: service book stamps, earlier listings and other records.
VIN match The VIN on the car matches the registration papers and the PPSR certificate.
Seller's licence The name and address match the registration papers.
Safety certificate In Queensland the seller needs a current safety certificate, and in Victoria a roadworthy certificate is needed to transfer the registration.
Receipt The date, the price, the VIN and rego, and both names and signatures.

Older cars also carry a compliance plate, usually under the bonnet or on a door pillar. A car supplied new since mid 2021 may have none: it is entered on the Register of Approved Vehicles instead.
