Small, light and simple: that’s why these cars are cheap to run. Here’s where the money goes, and how owners keep each bill down.
Fuel
The petrol cars have a 35-litre tank, so a fill from empty is a smaller hit than in most cars. Real-world economy depends on how and where you drive, but owners regularly see 50 mpg or more on a run, less in short-trip town driving and on cold mornings.
Where you fill up makes a surprising difference. Using the government’s Fuel Finder data, unleaded at motorway services has recently been around 24p a litre dearer than at supermarkets. Our fuel guide has the numbers, and the fuel prices page shows the cheapest near you or on your route.
The petrol engines are fine on standard E10 unleaded. There’s no need to pay for super unleaded unless you’ve got a modified car or prefer it. If in doubt, use the government’s E10 checker.
Insurance
The basic 60 PS cars sit in the very lowest insurance groups, which is a big reason they’re so popular with new drivers. More power and higher trims move up the groups, and the GTI sits noticeably higher, but it’s still reasonable for a hot hatch.
- Compare quotes every year rather than auto-renewing. Loyalty is rarely rewarded.
- Be accurate about modifications, even small ones like wheels. An undeclared modification can void a claim.
- Telematics (black box) policies can bring premiums down a lot for young drivers.
- Paying annually is usually cheaper than monthly, which often includes interest.
Road tax
How much Vehicle Excise Duty you pay depends on when the car was first registered. Cars first registered before April 2017 are taxed on their CO2 emissions, and many of these economical small cars sit in the cheapest bands. Cars registered from April 2017 pay the flat standard rate after the first year. Electric cars have paid road tax since April 2025, too.
Rates change each April, so check the exact figure for your car on GOV.UK or when you renew.
Servicing
These are simple cars, so servicing at a good independent garage is usually much cheaper than at a main dealer, and still keeps a proper history. A few things worth knowing:
- Use the oil specification in the handbook. The right oil matters more than the brand.
- The timing belt is checked at services rather than changed at a fixed interval. Ask your garage what they think of it, especially on an older or high-mileage car.
- Brake fluid needs changing every couple of years whatever the mileage.
- Keep every receipt. A full history adds real value when you sell.
Tyres, brakes and other wear
Narrow tyres on small wheels are cheap to replace compared with most cars, and a light car is kind to its brakes. The usual suspects for bills are clutches (especially on cars that spent their lives in town), suspension bushes and drop links, and air conditioning that needs regassing. None of it is expensive by modern standards.
Check your pressures
Under-inflated tyres wear faster and cost you fuel. The right pressures are on a sticker inside the fuel filler flap or the driver’s door frame. Check them monthly when the tyres are cold.
Keeping costs down
- Fill up at supermarkets and avoid motorway services. Plan longer trips with the journey planner.
- Drive smoothly. Gentle acceleration and reading the road ahead save more fuel than any gadget.
- Take the roof bars off and empty the boot when you’re not using them.
- Log your fill-ups on up mii go to see what you’re actually spending.
- Ask the forum before paying for a big job. Someone has usually done it and knows what it should cost.
