## Verdict

- **Best value year**: 2021
- **Ideal trim**: 300h F-Sport
- **Target mileage**: 40,000–60,000 miles
- **Max previous owners**: 2
- **Target price**: £18,500

## Why this model

The Lexus IS 300h is a fantastic choice if you're looking for a premium saloon that's incredibly reliable, comfortable, and surprisingly efficient. Lexus consistently tops reliability surveys, so you can expect very few headaches. The hybrid powertrain means good fuel economy, especially around town, and it offers a smooth, refined driving experience. It might not be as sporty as some German rivals, but it makes up for it with its serene cabin and bulletproof build quality.

## What you should pay

Based on current UK market trends for a 2021 Lexus IS 300h F-Sport with typical mileage (30-50k), a fair price is around £18,500. This reflects the strong demand for reliable hybrids and Lexus's excellent resale values, while also accounting for the general softening of the used car market since 2022-2023 peaks. Prices can vary slightly based on exact mileage, condition, and optional extras, but this is a solid target.

## Which trim to buy

The 300h F-Sport trim hits a real sweet spot. You get all the fantastic reliability and hybrid efficiency of the standard IS 300h, but with a much sportier look and feel thanks to the F-Sport styling, unique grille, and more supportive seats. It often includes desirable features like adaptive variable suspension (AVS) for a better ride/handling balance, and heated/ventilated seats, making it a more engaging and comfortable car without pushing the price into the top-tier Premier trim.

## What to check before you buy

- Infotainment system can be a bit fiddly to use for some
- 12V battery can drain if the car isn't driven regularly (common in hybrids)
- Rear brake wear can be a bit quicker than expected if not using regenerative braking effectively

## Running costs

Running costs for the IS 300h are quite reasonable for a premium car. Fuel economy is good, typically 45-55 mpg, which works out to about 13-15p per mile with petrol at current prices. Road tax (VED) for a 2021 model will be £560 per year for the first 6 years (due to its new price being over £40k), then it drops to £170 per year. Insurance is moderate, usually falling into Group 30-35, so get a few quotes. Servicing costs are competitive, especially compared to its German rivals, and parts are readily available.

## Key stats

- **Fuel Type**: Hybrid
- **Horsepower**: 223 hp (combined)
- **Mpg**: 45-55 mpg
- **Reliability Score**: Excellent
- **Safety Rating**: 5-star Euro NCAP

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £18,500 | 100% |
| 2027 | £16,465 | 89% |
| 2028 | £14,983 | 81% |
| 2029 | £13,784 | 74% |
| 2030 | £12,819 | 69% |

The Lexus IS 300h holds its value remarkably well compared to many rivals. The sweet spot for buying used is typically around 3-5 years old, as the initial steep depreciation has already occurred. For selling, you'll find good retention even after 5-7 years, making it a smart long-term purchase. Its reputation for reliability keeps demand high.

Total value lost since new: 31%.

## Alternatives to consider

- BMW 3 Series (330e)
- Audi A4 (40 TFSI)
- Mercedes-Benz C-Class (C300h)
