## Verdict

- **Best value year**: 2018
- **Ideal trim**: Premium
- **Target mileage**: 40,000–70,000 miles
- **Max previous owners**: 3
- **Target price**: £10,500

## Why this model

The Infiniti Q30 is a bit of a hidden gem! It's essentially a stylish, more distinctive take on the Mercedes-Benz A-Class, as it shares its platform and many components. This means you get Mercedes engineering and comfort, but often at a more attractive price point on the used market. It's comfortable, handles well, and has a premium feel inside. Since it's been discontinued, it offers great value now that the initial steep depreciation has passed.

## What you should pay

For a 2018 model, you should be looking to pay around £10,500 for a well-maintained 'Premium' trim with average mileage. Prices for the Q30 have stabilised significantly since its discontinuation, making it a smart buy now. You'll find a range from about £8,000 for older, higher mileage SE models up to £13,000 for a top-spec 'Sport' from 2019.

## Which trim to buy

The 'Premium' trim hits the sweet spot for the Q30. It adds desirable features like 18-inch alloy wheels, dual-zone climate control, heated front seats, and rear parking sensors, which really enhance the comfort and convenience without pushing the price up too much like the 'Sport Tech' models. It feels genuinely premium without being overly flashy.

## What to check before you buy

- Infotainment system can feel a bit dated compared to newer cars
- Some owners report minor electrical gremlins, similar to its Mercedes A-Class platform sibling
- Diesel Particulate Filter (DPF) issues if mainly used for short, urban journeys
- Brake wear can be higher due to the car's weight

## Running costs

For the 2.2d diesel engine, you can expect fuel costs of around 14p per mile based on current diesel prices and its typical 50-55 mpg. Road tax (VED) for a 2018 diesel model will be around £180 per year. Insurance costs are generally moderate, but as always, this can vary significantly based on your personal circumstances.

## Key stats

- **Fuel Type**: Diesel
- **Horsepower**: 168hp
- **Mpg**: 50-55 mpg
- **Reliability Score**: Above Average
- **Safety Rating**: 5-star Euro NCAP (2015)

## Trim comparison

| Trim | Price new | Price used | Key features |
| --- | --- | --- | --- |
| SE | £20,500 | £8,000 | 17-inch alloy wheels; LED daytime running lights; Cruise control |
| Premium | £23,000 | £10,500 | 18-inch alloy wheels; Dual-zone climate control; Rear parking sensors |
| Sport | £25,000 | £12,000 | 19-inch alloy wheels; Sport suspension; Unique front and rear bumpers |

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £10,500 | 0% |
| 2027 | £9,500 | 9.5% |
| 2028 | £8,500 | 19% |
| 2029 | £7,500 | 28.5% |
| 2030 | £6,500 | 38.1% |

Buying a Q30 now means you're past the steepest part of its depreciation curve. As it's already an older, discontinued model, its value will drop at a much slower rate compared to a newer car, making it a good value proposition for long-term ownership. You're unlikely to lose a huge percentage of its value in the coming years.

Total value lost since new: 38.1%.
