The BMW 6-series is looking increasingly like a secondhand bargain - here autocar.co.uk guides you through the buying process.
Our expert advice comes from Dermot Dromey, owner of Southampton-based independent BMW servicing specialist Bartley's.

"I'd buy a 3.0-litre, six-cylinder petrol," he says. "They seem to be more reliable than both the V8 and the diesel."
Body
Faulty electric window sensors can cause the electric windows to close slowly - or not at all. Look out for corrosion or discolouration on the window chrome too. But there shouldn’t be any sign of rust. If there is, it’s bound to be a sign of a poor repair.
Electrics
If it has a head-up display, be sure that it works; malfunctions can result from damage to the car’s wiring loom. Also be aware of auto headlights that don’t switch off and gearbox paddle shifters with bad connections.
Suspension
There was a recall about rear shock absorber mounting failures in 2006. Another recall in 2008 warned against the rear axle carrier failing, so be vigilant for both. Rear knuckle joints should be changed at 50,000 miles, costing about £300
Wheels and tyres
The run-flats fitted to 6-series as standard are prone to punctures. They’re impossible to repair, don’t last long and are £300 each to replace. And they can do real damage to a wheel when they deflate. Best advice? Junk them and fit ordinary rubber.
Engine
If you’ve got a ‘check engine’ light on your dash, it could be that your camshaft position sensors need replacing. Leaking oil lines to valve timing units have been reported, as have cracked hoses, oil caps and valve covers.

You did not say what to pay for the thing, though.
