Cheap-to-run used cars: what to look for under £5,000

The costs that matter after you buy (tax, insurance, fuel, servicing and clean air zones) and the small cars that keep them low.

The costs that matter

The price on the windscreen is only the start. Over a few years, tax, insurance, fuel, servicing and tyres can add up to more than you paid for the car, so a slightly dearer car that’s cheaper to run can be the better buy. Here’s what to look at.

Road tax

For cars first registered between March 2001 and March 2017, road tax (vehicle excise duty) is based on the car’s CO2 emissions. That makes many small, efficient cars from those years very cheap to tax. Cars registered from April 2017 pay a flat standard rate after the first year, whatever their emissions. You can check the exact rate for any car on GOV.UK using its registration.

Insurance

Every car sits in an insurance group from 1 (cheapest) to 50. Small hatchbacks with small engines and basic trims are usually in the lowest groups, which is why they’re popular first cars. Your age, postcode, job and record matter as much as the car, so get a quote on the exact registration before you commit.

Fuel and engine size

Small, modern petrol engines, such as 1.0 and 1.2-litre three-cylinders, are light on fuel for town driving and short trips. Diesels can be more economical on long motorway runs, but they suit high mileages better than short hops, and older diesels may not be clean air zone compliant.

Servicing, tyres and parts

Popular small cars are cheap to look after: parts are plentiful, most garages know them well, and their smaller wheels take less expensive tyres. A full service history, a fresh service and a long MOT at purchase also mean fewer surprises in your first year.

Small cars that keep costs down

These are the kinds of cars we specialise in. They’re small, popular and cheap to run, and each one we sell comes with at least 3 months’ warranty, a 75-point check and a minimum of 9 months’ MOT:

A quick checklist

  1. Check the road tax on GOV.UK.
  2. Get an insurance quote on the exact registration.
  3. Check the MOT history, and how long the MOT is when you buy.
  4. Ask about the service history and the next service due.
  5. Check the tyres, and how much a set costs for that size.
  6. If you drive in Birmingham or London, check the car is clean air zone compliant.

Quick answers

What is the cheapest type of used car to run?

Generally a small petrol hatchback with a small engine: cheap to insure, light on fuel, inexpensive tyres and parts, and usually compliant with clean air zones. The exact costs depend on the car and on you, so check tax and get insurance quotes before you buy.

Is road tax cheaper on older cars?

For cars first registered between March 2001 and March 2017, road tax is based on CO2 emissions, so many small, efficient cars from those years are cheap to tax. Cars registered from April 2017 pay a flat standard rate after the first year. Check the exact rate for a car on GOV.UK.

Which used cars are cheapest to insure?

Cars in low insurance groups, typically small hatchbacks with small engines and basic trims. Your age, postcode and record matter just as much, so get quotes on the exact car before you buy.
