## Why this model

The Vauxhall Astra is a solid choice if you're looking for a practical, comfortable, and good-value hatchback. It's often overlooked compared to the Golf or Focus, which means you can usually snag a better deal. It's got a decent boot, handles well enough for everyday driving, and the petrol engines are generally efficient and reliable. It's a sensible, no-nonsense car that won't break the bank to buy or run.

## What you should pay

Based on current UK market trends (February 2026), a 2021 Vauxhall Astra in a popular mid-range trim like SRi Nav, with around 30,000-45,000 miles, should realistically be priced around £12,500-£13,500. Prices have softened slightly for mainstream petrol cars, making it a good time to buy. Always compare prices across AutoTrader and Motors.co.uk to ensure you're getting a fair deal.

## Which trim to buy

The SRi Nav trim is often the sweet spot for the Astra. It adds a sportier look with bigger wheels and body styling, plus you get essential features like sat-nav, front and rear parking sensors, and automatic lights and wipers. It feels a bit more special than the entry-level models without pushing the price too high, offering a great balance of features, comfort, and value for money.

## What to check before you buy

- Infotainment system glitches (freezes, slow response)
- Rear suspension noise (bushes or top mounts)
- Some reports of timing chain wear on higher mileage 1.4T/1.6T engines
- Brake judder (check discs and pads)

## Running costs

Running a 2021 petrol Astra is pretty affordable. Fuel costs for a 1.2 or 1.4 turbo engine will be around 14-16 pence per mile, assuming 45-50 mpg and petrol at £1.50/litre. Road tax (VED) for a 2021 model is typically around £180-£190 per year, depending on the specific CO2 emissions. Insurance will vary based on your age, location, and driving history, but it's generally in a reasonable group for a family hatchback.

## Key stats

- **Fuel Type**: Petrol
- **Horsepower**: 110-145 hp
- **Mpg**: 45-55 mpg
- **Reliability Score**: Average
- **Safety Rating**: 5-star Euro NCAP (2015)

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £13,000 | 100% |
| 2027 | £11,050 | 85% |
| 2028 | £9,490 | 73% |
| 2029 | £8,320 | 64% |
| 2030 | £7,410 | 57% |

Buying a 2021 Astra now means you're picking it up after the steepest part of its depreciation curve has passed. It's still modern enough to feel current but old enough to offer significant savings over a new model. You'll likely see a slower rate of value loss over the next few years compared to buying a newer car.

Total value lost since new: 43%.
