## Why this model

⚠️ Limited UK data — Kia EV9 only arrived in the UK in late 2023/early 2024, so we have fewer MOT tests and less resale history than established brands. However, the EV9 is a fantastic choice for families needing space and range. It's got a striking design, a huge, practical interior with up to seven seats, and a very impressive real-world range. Kia's 7-year warranty gives great peace of mind, and its fast charging capabilities make longer trips much easier.

## What you should pay

The Kia EV9 is a very new model, so used examples are just starting to appear. Based on current market trends for large premium EVs and the provided anchor, a well-maintained 2024 GT-Line with around 10,000-20,000 miles should be around £51,998. Due to its newness and the evolving EV market, expect a wider price range of ±20%, meaning prices could realistically be between £41,598 and £62,398 depending on condition, mileage, and specific options. This reflects the initial depreciation from new, but also its strong appeal and advanced tech. The 99.8kWh liquid-cooled battery is robust, with expected degradation of only ~1.8% per year, meaning a 2-year-old model should still have over 96% of its original capacity.

## Which trim to buy

The GT-Line trim offers a fantastic balance of luxury, technology, and value. It comes packed with features like advanced driver assistance, premium sound, and larger screens, without the top-tier price tag of the GT-Line S. You get most of the desirable upgrades that make the EV9 feel truly premium, making it the sweet spot for a used purchase.

## What to check before you buy

- As a very new model, widespread common faults aren't yet established. However, with any new EV, it's wise to check for software glitches (ensure all updates are applied), proper functioning of all advanced driver-assistance systems, and consistent charging performance. Inspect the charging port for any damage and ensure the 12V auxiliary battery is in good health, as these can sometimes be overlooked. Also, check for any early recall notices, though Kia's build quality is generally excellent.

## Running costs

Running an EV9 can be very cost-effective, especially if you can charge at home on a smart tariff. At a standard home rate (Ofgem cap 24.5p/kWh), you're looking at about 9p/mile, which is roughly £902 per year for 10,000 miles. However, with a smart EV tariff like Octopus Go or Intelligent Octopus (around 9p/kWh overnight), this drops significantly to about 3.3p/mile, costing only around £331 per year for 10,000 miles. That's a saving of over £570 a year! Road tax for EVs is currently free until April 2025, after which it will be £195 per year. Insurance will be on the higher side due to the car's value and performance, likely in the £800-£1,500 range depending on your personal circumstances.

## Key stats

- **Fuel Type**: Electric
- **Horsepower**: 378 hp
- **Mpg**: N/A (Electric)
- **Reliability Score**: Excellent (Kia's 7-year warranty)
- **Safety Rating**: 5-star Euro NCAP (2023)

## Trim comparison

| Trim | Price new | Price used | Key features |
| --- | --- | --- | --- |
| Air | £65,000 | £45,000 | 19-inch alloy wheels; LED lighting; Three-zone climate control |
| GT-Line | £73,000 | £51,998 | 21-inch alloy wheels; GT-Line exterior styling; Upgraded sound system |
| GT-Line S | £76,000 | £55,000 | Digital side mirrors; Head-up display; Relaxation seats |

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £51,998 | 100% |
| 2027 | £44,198 | 85% |
| 2028 | £39,778 | 76.5% |
| 2029 | £36,596 | 70.4% |
| 2030 | £34,034 | 65.4% |

The EV9 is so new that the 'sweet spot' for buying used is just starting to emerge. Buying a 1-2 year old model (like a 2024 in 2026) means you let the first owner take the biggest hit of depreciation. While it will continue to depreciate, the initial steep drop has already occurred, offering better value for money compared to buying new.

Total value lost since new: 34.55%.
