2015 BMW I3 0.6L Hybrid electric · AD15 OPJ

The BMW i3 with the range-extender returns roughly 60-70 mpg in mixed driving and significantly more in pure electric mode if charged regularly, making it one of the cheapest BMWs to run on a per-mile basis. Road tax is free as a hybrid electric, and insurance typically falls into group 21-28 depending on variant — moderate but not the cheapest.

Annual servicing tends to cost £200-£400 at independent BMW specialists, though main dealer servicing can exceed £500. Tyres are an ongoing cost — premium EV-rated tyres run £120-£180 per corner fitted. The estimated annual running cost, excluding depreciation, is £800-£1,100.

The August 2024 MOT failure flagged a front windscreen wiper not clearing effectively and an offside front headlamp aim too low. Inspect both systems: confirm wiper arms and blades operate correctly across the full sweep, and verify headlamp alignment is within tolerance. Check headlamp mounting points for cracks or previous damage, as the 'too low' advisory can indicate mounting bracket wear or accident damage.

The 2026 advisories for tyre perishing on three corners and a defective rear fog lamp lens should be inspected in person. Check all four tyres for sidewall cracking, and confirm the rear fog lamp lens is intact and the bulb functions — both are simple fixes but indicate the car has been lightly neglected cosmetically. Known i3 weak points include the high-voltage battery degradation (especially in cars over 8 years old), the range-extender engine's auxiliary belt, and the suspension bushes, so inspect for clonks over speed bumps and uneven tyre wear.
