Used BMW iX Buying Guide
The BMW iX (2021 on) is the brand’s electric flagship SUV: a ground-up EV with a carbon-and-aluminium structure, a lounge-like minimalist cabin and looks that people either love or absolutely don’t. Ignore the styling debate and you’ll find one of the most refined, comfortable electric cars of its generation. Heavy depreciation from a very high launch price makes used examples striking value. It suits families and long-distance drivers who want first-class EV travel with home charging, and it remains one of the quietest cars of any kind at motorway speed.
Engines and trims
Three versions dominate. The xDrive40 pairs twin motors (around 322bhp) with a battery of roughly 76kWh gross - fine for regional use but the shortest-legged of the range. The xDrive50 is the sweet spot: around 516bhp and a circa-111kWh battery giving an official range well beyond 350 miles and genuinely long real-world legs, plus faster peak DC charging (up to about 195kW versus around 150kW for the 40). The M60 adds pace you’ll rarely use. UK trims run Sport and M Sport, both generously equipped; desirable extras include the Sky Lounge electrochromic roof, Bowers & Wilkins audio, soft-close doors and the full Driving Assistant Professional suite. The 2025-on facelift renamed and upgraded the line-up with more range across the board. Whichever version you choose, the interplay of light steering, huge refinement and rear-wheel steering (on higher specs) makes the iX feel far smaller than it is.
What to check before buying
Get battery evidence first: a BMW battery health certificate or independent state-of-health check, and a full-charge indicated range compared with the version’s official figure. The high-voltage battery typically carries eight-year/100,000-mile cover from first registration - confirm what remains. Test AC and DC charging, check both cables are present, and make sure over-the-air software updates have been applied; early cars had their share of software gremlins affecting infotainment and assistance systems, mostly resolved by updates.
Physically, inspect the enormous alloys for kerbing and the tyres for even wear - the iX is heavy and hard on rubber when misaligned. Air suspension (fitted to higher versions) should self-level and stay up overnight. Interior materials are unusual - open-pore wood, fabric and crystal-effect controls - so check for wear and scratches that may be costly to put right. The frameless doors should shut with a solid thunk and seal silently at speed, and the huge windscreen’s camera systems must be calibrated correctly after any glass replacement - ask for paperwork if a new screen has been fitted.
Running costs
Home charging makes a big luxury SUV astonishingly cheap to fuel; regular public rapid charging narrows the gap considerably, so match the version to your charging reality. Insurance sits in the top groups and premium tyres in large sizes are the standout consumable. Servicing is inspection-based and typically cheaper than a combustion X5, and remaining battery warranty softens the biggest ownership risk. Check windscreen cover on your insurance policy too - that vast, sensor-laden screen is an expensive item to replace.
Verdict
The used iX is a depreciation-powered bargain: flagship refinement, huge range in xDrive50 form and a cabin like nothing else German. Buy on battery health, software currency and tyre condition, and it’s a supremely relaxing way to go electric.
