To fit more neatly into the gap between the X1 and the X5, the X3 grew in its second generation guise, 78mm longer and 28mm wider than its predecessor, yet rather impressively, running out 25kg lighter. As importantly, the rather gawky looks of the MK1 model were replaced by a far more cohesive piece of design that looks lower and more purposeful, differentiated from the larger X5 by squared-off front headlamps and a strong character line scalloped into the side flanks.
Thunking shut one of the doors is your first clue as to the quality improvements that doubtless were a part of the move from contracting out production of the MK1 model to Magna Steyr in Austria and producing this one in-house at BMW's Spartanburg factory in the US. The cabin certainly feels like one befitting a premium mid-sized SUV and the MK2 design's significantly enhanced leg and elbow room means that two adults can be relatively comfortably seated in the rear, provided that they don't have to share their space with a third person who, thanks to the proximity of the transmission tunnel, will only really be comfortable on short journeys.
The rear bench itself hasn't any fancy sliding, reclining or removable tricks, but original owners could specify its push-button folding mechanism in 40:20:40 form to offer a bit more flexibility when increasing the size of the 550-litre boot to 1500-litres by folding the back chairs forward. So, yes, whether you need to transport dogs, flat-pack furniture - or even a mountain bike with both wheels attached, it will probably fit.
At the wheel, the dash and seating position are just tall enough for your perch to feel SUV-like and the leather-lined, beautifully finished cabin feels an up-market place to be, dominated by its standard 6.5-inch colour iDrive display screen, upgraded to 8.8 inches with the Professional Multimedia package many original owners specified. The iDrive control is down by the gearstick and is supplemented by extra buttons to make it easier for you to find everything from navigation to ventilation.
What To Look For
Our ownership survey uncovered a number of satisfied customers, but also a number who'd had teething issues. One car exhibited a knocking noise from the front right, traced to a faulty steering rack. In fact, no fewer than four replacement racks were needed on that particular model; apparently, it's due to a design fault. On owner reported a buzzing sound from the back end of the car, while another talked of transfer case whine (a £2,000 fix) and yet another said he'd noticed occasional screeching from the engine. Look out for all these things on your test drive. Other failures related to the front door latch, the rear boot latch, the trip computer, the tow bar and the Bluetooth module; check all of these. One owner found his car's front brake discs needed prematurely replacing. Another reported a rattly sunroof and door seals that squeaked.
As usual, make sure that servicing has been correctly carried out at a BMW main dealer. Given this X3's 'crossover' rather than full-SUV status, it's unlikely than any given car will have been subjected to any off-road heroics, but check around the sills just in case. Kerbed alloy wheels and signs of interior child damage are much more likely. Use these as negotiating points with the seller.
(approx based on a 2015 X3 20d xDrive 190bhp excl. VAT) A pair of brake pads are between £28-£35 for cheap brands and between £50 and £70 (or even as much as £93) if you want an expensive make. A pair of brake discs start in the £60 to £80 bracket, but you can pay in the £112 to £150 bracket for pricier brands. A drive belt is around £15. Air filters sit in the £22 bracket. Oil filters cost around £15. Fuel filters sit in the £27 to £22 bracket. A wiper blade sits in the £8 to £17 bracket. A headlight is about £360 and a mirror glass sits in the £25 to £28 bracket, but you can pay in the £42 to £44 bracket for pricier brands
Settle behind the wheel and get ready to punch the starter button and you've that pleasant compromise between a perch that's higher than it would be in an ordinary saloon, yet one still low enough to make you feel a part of the whole driving experience. The X3 range was an all-diesel affair in MK2 guise, with the majority of buyers opting for the four cylinder 20d xDrive variant, initially offered with 184bhp, the engine later uprated to 190bhp. In 2012, a 2WD sDrive 18d variant using the same engine de-tuned to 143bhp was added to the range. Two auto-only six cylinder xDrive models were also offered, a 258bhp xDrive 30d and a 313bhp xDrive 35d.
BMW has always been proud of this model's xDrive permanent four-wheel technology, but as you might expect, the engineering behind it was mainly devoted to the business of making this mid-sized SUV handle just like a BMW 3 Series Sports saloon. Certainly, the way that this electronically controlled system can distribute torque as needed to all four wheels depending on the grip at either front or rear will be useful in a snowy snap. It's really there though, to make ordinary, everyday tarmac motoring that bit more enjoyable, helping to control the car through bends by, in true BMW style, sending more power rearwards and, if necessary, even lightly braking the inside rear wheel in tight cornering to increase mid-bend agility and traction.
As for the rocky ride that owners of the MK1 version of this model might remember, well things are much improved here, with a redesigned independent set-up offering a far more compliant set-up. Indeed, it's one you can exercise some control over yourself if you get a car whose original owner ticked the extra cost box for the Variable Damper Control that comes with BMW's Drive Dynamic Control System. Here, you can switch between 'Normal', 'Sport' and 'Sport+' modes via this dashboard button, allowing the electronics to adjust the character of throttle settings, engine response and DSC stability control thresholds, depending on the road you're on and the mood you're in. The system also alters power steering weight, which you might feel will make unnecessary the further extra cost options of Servotronic or Variable-ratio sports steering that offer fingertip-lightness when parking but greater feel through faster corners.
We should also mention that the Variable Damper Control can also alter the characteristics of the optional 8-speed automatic transmission, the gearbox many original owners chose. Try an X3 with the satisfyingly slick 6-speed manual 'box first before committing to it though. What else? Well refinement is exemplary on the motorway, while at the other extreme, this car will cope quite happily with muddy tracks that don't trouble the relatively shallow ground clearance. And in the unlikely event that you're tackling a steepish, slimy slope, a Hill Descent Control system will allow you to pick your way carefully down it.
This X3 came of age in second generation guise, an immeasurable improvement over the MK1 version in every possible way. Even the best of this car's prestige rivals from this era struggled to match this one's hugely impressive blend of performance and efficiency. It feels up-market, it rides impressively and, thank goodness, on-tarmac, it drives just as a BMW should.
All of which means that used SUV buyers in this sector who can afford the asking prices should find that this X3 adds up very nicely indeed. Assuming that they don't prioritise off road ability of course, but then in that case, it's fair to ask whether a larger but more conventional 2WD BMW 520d Touring for around the same kind of money wouldn't be a better bet. It comes down to personal preference - and we're guessing that's a choice you'll enjoy making.
