## Verdict

- **Best value year**: 2021

- **Target mileage**: 40,000–60,000 miles
- **Max previous owners**: 2
- **Target price**: £35,493

## Why this model

The Audi Q7 is a fantastic choice if you're looking for a large, luxurious, and practical SUV. It offers a premium interior, comfortable ride, and Audi's renowned Quattro all-wheel-drive system, making it great for all weather conditions and family duties. The 50 TDI diesel engine provides a good balance of power and reasonable fuel economy for its size, making it a strong contender for longer journeys.

## What you should pay

Based on current UK market data (February 2026), a 3-4 year old Audi Q7 S Line 50 TDI with around 30,000-50,000 miles typically sells for around £35,493. Prices can vary by ±15% depending on specific mileage, condition, optional extras, and dealer. Expect to pay a bit less for a 'Sport' trim and more for a 'Black Edition' or a model with highly desirable optional extras like a panoramic roof or advanced driver assistance packs.

## Which trim to buy

The S Line trim is generally the sweet spot for the Q7. It adds a sportier look with more aggressive bumpers and larger alloy wheels, along with upgraded interior features like sport seats and often more advanced lighting. It strikes a great balance between the entry-level 'Sport' trim's practicality and the 'Black Edition's' aesthetic upgrades, offering excellent value without the higher price tag of the top-tier models.

## What to check before you buy

- Air suspension problems (leaks, compressor failure)
- MMI (infotainment) system glitches or freezing
- DPF (Diesel Particulate Filter) issues on diesel models, especially with short journeys
- AdBlue system faults
- Electrical gremlins (sensors, warning lights)
- Heavy brake wear due to vehicle weight

## Running costs

For a 2021 Audi Q7 50 TDI, running costs include: Fuel: At current diesel prices (~£1.55/litre) and around 35 mpg, expect to pay roughly £0.19 per mile.
