## Why this model

The Suzuki SX4 S-Cross is a really sensible choice if you're looking for a practical, reliable, and economical compact SUV. It's not the flashiest car out there, but it's built to last, offers good space for its size, and the mild-hybrid engine keeps running costs down. It's a no-nonsense car that just gets on with the job, making it a great value proposition on the used market.

## What you should pay

Based on current UK market data for February 2026, a 2021 Suzuki SX4 S-Cross SZ5 BoosterJet with around 30-50k miles typically sells for about £14,292. This is a strong price for a well-equipped, reliable crossover. Lower trims like the SZ-T or SZ4 will be a bit cheaper, but the SZ5 offers excellent value for the extra features you get.

## Which trim to buy

The SZ5 trim is definitely the one to go for if you can find it. On the used market, the price difference between the SZ-T and SZ5 isn't huge, but the SZ5 adds some lovely creature comforts like leather upholstery, a panoramic sunroof, and LED headlights. It really makes the car feel a bit more premium without breaking the bank, giving you the best bang for your buck.

## What to check before you buy

- Generally very reliable, but some owners have reported minor electrical glitches (e.g., infotainment system freezing) that can often be resolved with software updates.
- Occasional clutch wear on manual models at higher mileages, so check for smooth gear changes and no slipping.

## Running costs

Fuel: With the 1.4 BoosterJet Mild Hybrid engine, you can expect around 50 mpg, which translates to roughly 13-14p per mile with current petrol prices. VED (road tax): For a mild hybrid registered after April 2017, it's typically £180 per year. Insurance: Expect to pay in the region of £450-£650 annually, though this can vary significantly based on your personal circumstances, postcode, and no-claims bonus.

## Key stats

- **Fuel Type**: Mild Hybrid
- **Horsepower**: 129 hp
- **Mpg**: 50-52 mpg
- **Reliability Score**: Excellent (4.5/5)
- **Safety Rating**: 5 Stars (Euro NCAP)

## Depreciation forecast

| 2026 | £14,292 | 100% |

Buying a 2021 S-Cross in 2026 means you're getting a car that's already taken the biggest hit in depreciation. The initial steep drop from new has passed, and Suzuki's reputation for reliability helps it hold its value better than some rivals in the long run. You're buying into a stable part of its ownership cycle.

Total value lost since new: 30%.
