## Why this model

The BMW iX3 is a fantastic choice if you're looking for a premium electric SUV that blends BMW's renowned driving dynamics with zero-emission motoring. It's essentially an electric X3, so you get a familiar, comfortable, and well-built interior, along with a smooth and powerful electric drivetrain. The 74kWh usable battery provides a decent real-world range, and with liquid cooling, the battery health tends to hold up very well, with an expected degradation of only about 1.8% per year. It's a solid, reliable EV that offers a great balance of luxury, practicality, and efficiency.

## What you should pay

The used EV market has seen some significant adjustments recently, making cars like the iX3 much more accessible. A 2021 BMW iX3 Premier Edition Pro with around 30-45k miles is currently sitting around the £23,990 mark. This represents excellent value compared to its new price, especially considering its premium badge and features. The market has softened, so you're buying at a good time to get more for your money.

## Which trim to buy

The 'Premier Edition Pro' trim offers the best balance of features and value. It comes packed with goodies like a panoramic sunroof, adaptive suspension, a head-up display, and a Harman Kardon sound system, which really elevate the driving experience without pushing the price too high. You get all the desirable tech and comfort features that make a BMW feel premium, without paying the extra for the 'M Sport Pro' which often adds more cosmetic enhancements than essential upgrades for a used buyer.

## What to check before you buy

- Tyre wear can be higher due to the weight and instant torque of EVs, so check tyre condition carefully.
- Minor software glitches are possible, ensure all infotainment features work smoothly.
- Check the 12V auxiliary battery, as these can sometimes fail prematurely in EVs, though less common in modern BMWs.

## Running costs

Running an iX3 can be very cost-effective, especially if you can charge at home. Based on real-world efficiency of about 3 mi/kWh: if you're on a standard home electricity rate (around 24.5p/kWh), it'll cost you roughly 8.1p per mile, or about £813 a year for 10,000 miles. However, if you switch to a smart EV tariff like Octopus Go or Intelligent Octopus (around 9p/kWh overnight), that drops to just 3p per mile, or about £299 a year for 10,000 miles – saving you over £500 annually! Road tax is free until April 2025, after which it will be £195 per year. Insurance costs will vary but expect to pay between £600-£1000 annually, depending on your personal circumstances.

## Key stats

- **Fuel Type**: Electric
- **Horsepower**: 282 hp

Buying a 2021 iX3 now means you're past the steepest part of its depreciation curve. The initial drop from new has already happened, largely influenced by the broader EV market adjustments. While it will continue to depreciate, the rate should slow down, making it a more stable investment for the next few years compared to buying new.

Total value lost since new: 31.5%.
