BMW X5 Used Car Review

BMW's reputation for building engaging driver's cars meant it probably shouldn't have been a surprise when it set the standard for SUV handling with its first effort, the 2000 X5. Over two successive generations, it has grown in size, added a third-row option (since 2007), and introduced a rear-wheel-drive variant (since 2013). One of BMW's biggest-selling models, the X5 range covers a broad spectrum of engines including an eco-focused hybrid and performance-biased M model.

Pros

Cons

  • One of the best SUVs to drive in terms of handling
  • Wide range of engines from economical 4-cylinder diesel to powerful V8
  • Cabin and boot space further enlarged with third generation (2013 on)
  • Intuitive and smartly presented iDrive infotainment system
  • Latest X5 doesn't ride or steer as well as previous generations
  • Interior has improved though has yet to set any segment benchmark
  • Limited boot space with seven-seater option
  • Bulkier, US-focused styling of current model
This is general information and should not be relied on as purchasing advice.

SIMILAR MODELS TO BMW X5

WHAT TO LOOK OUT FOR: BMW X5 (2013 ONWARDS)

Like any quasi off-roader, the X5 needs a close check to make sure it hasn't been driven in inappropriate terrain.

Luckily, most of them were used as family cars, and that's the one you want to buy provided the interior hasn't been trashed by kids, dogs and mountain bikes.

Mechanically, the big thing to watch out for is an engine that has experienced patchy maintenance.

The VANOS variable valve-timing arrangement in the engine is one of the things that gives the X5 its performance, though skipped oil changes can lead to dirty oil that will clog the delicate little oilways that operate the system.

If the VANOS hardware quits, it's big dollars to fix.

Check for oil leaks anywhere around the VANOS actuators (at the front of the engine) for signs of oil weeping, which can be (but isn't always) the first sign of trouble.
