The Ford Fiesta has long been a favourite among UK drivers, and for good reason. This little hatchback is not just fun to drive; it also boasts impressive fuel economy figures. Depending on the engine variant, you can achieve around 60-70 mpg, making it a top contender for those looking to save at the pump.

With prices often starting around £5,000 for a well-maintained model, the Fiesta is an affordable option that doesn’t skimp on quality. Just make sure to check the MOT history to ensure you're not buying a lemon.
2. Volkswagen Polo
The Volkswagen Polo is another excellent choice for those seeking a used car with low fuel costs. Known for its build quality and reliability, the Polo can deliver around 60-65 mpg, depending on the engine. It’s a bit pricier than the Fiesta, with used models typically starting at around £6,000, but you’re paying for that solid German engineering.
One of the Polo's standout features is its spacious interior, which feels more premium than you might expect in this price range. It also comes with a good selection of tech features, making it a great option for tech-savvy drivers. Just like with the Fiesta, be sure to check the DVLA vehicle check for any hidden issues.
3. Toyota Yaris
If reliability is your top priority, the Toyota Yaris should be on your radar. This supermini is renowned for its durability and low running costs, often achieving around 55-65 mpg. The Yaris is particularly appealing for city driving, thanks to its compact size and nimble handling.
Prices for used Yaris models start around £4,500, making it a budget-friendly option. The interior is straightforward and functional, which is perfect for those who appreciate practicality over flashiness. Plus, Toyota’s reputation for reliability means you’re less likely to face unexpected repair bills.
4. Hyundai i20
The Hyundai i20 is often overlooked, but it’s a hidden gem in the used car market. This hatchback offers a comfortable ride and impressive fuel efficiency, with many models achieving around 60 mpg. Starting prices are typically around £5,500, making it a solid choice for budget-conscious buyers.
One of the i20's strengths is its generous warranty coverage, which can often be transferred to second-hand buyers. This adds an extra layer of peace of mind, knowing that you’re covered for any potential issues. Additionally, the i20 has a spacious boot, making it suitable for families or those who need extra storage.
5. Skoda Fabia
The Skoda Fabia is another underrated option that deserves a mention. With fuel economy figures similar to the Polo, the Fabia can achieve around 60-70 mpg. It’s known for its practicality, offering a surprisingly roomy interior and a large boot for a small car.
Used prices for the Fabia start around £5,000, making it an affordable alternative to more mainstream models. Skoda has a reputation for building reliable cars, and the Fabia is no exception. Just be sure to check for service history to ensure it’s been well-maintained.
Comparing Fuel Efficiency and Features
Let’s take a closer look at how these cars stack up against each other in terms of fuel efficiency, insurance costs, and practicality. Here’s a quick comparison table to help you make a more informed decision:
| Model | Fuel Economy (mpg) | Starting Price (£) | Boot Space (litres) | Insurance Group |
|---|---|---|---|---|
| Ford Fiesta | 60-70 | 5,000 | 292 | 10 |
| Volkswagen Polo | 60-65 | 6,000 | 351 | 11 |
| Toyota Yaris | 55-65 | 4,500 | 286 | 9 |
| Hyundai i20 | 60 | 5,500 | 326 | 10 |

From this comparison, you can see that the Ford Fiesta and Skoda Fabia lead the pack in terms of fuel economy, while the Volkswagen Polo offers a bit more boot space. The Toyota Yaris stands out with its lower insurance group, making it an attractive option for younger drivers or those looking to keep their overall costs down.
Real-World Ownership Reality
When buying a used car, it’s essential to consider what can go wrong and what typical MOT history looks like for these models. Generally, cars in this price range are reliable, but there are common issues to be aware of.
For instance, the Ford Fiesta has been known to have problems with the clutch and gearbox, particularly in older models. Regular servicing can help mitigate these issues, so always check the service history. The Volkswagen Polo, while reliable, can sometimes suffer from electrical issues, particularly with the infotainment systems.
The Toyota Yaris is often praised for its reliability, but some owners have reported issues with the hybrid battery in older models. The Hyundai i20 and Skoda Fabia are generally robust, but it’s worth checking for any signs of bodywork rust, especially in older vehicles.
Common Traps and False Economies
While it’s tempting to go for the cheapest option available, some cars that appear to be bargains can end up costing you more in the long run. For example, older diesel models may seem like a good deal due to their fuel efficiency, but they can incur hefty repair bills and higher road tax costs due to emissions regulations.
Additionally, some cars may have a lower purchase price but come with higher insurance premiums or servicing costs. Always consider the total cost of ownership, including insurance, servicing, and potential repairs. Checking resources like Thatcham insurance groups can help you gauge what to expect.
Running Cost Reality Check
Let’s break down the running costs for our top picks. Fuel costs will vary based on your driving habits, but here’s a rough estimate based on average fuel prices and mileage:
- Ford Fiesta: With an average fuel price of around £1.40 per litre, driving 10,000 miles a year could cost you approximately £1,000 in fuel.
- Volkswagen Polo: Expect similar costs, but slightly higher due to its marginally lower mpg.
- Toyota Yaris: With its excellent fuel economy, you might spend around £900 annually on fuel.
- Hyundai i20: Similar to the Yaris, around £900 per year.
- Skoda Fabia: Again, expect costs around £1,000, depending on your driving style.
Insurance costs will vary based on your personal circumstances, but generally, the Yaris and Fabia are likely to be cheaper to insure due to their lower insurance groups. Always get a few quotes before making a decision.
