The cheapest first car to buy is often not the cheapest to own. For a new driver in the UK or Ireland, insurance is often the biggest yearly cost, so compare the exact vehicle and its total yearly cost before you hand over any money. This guide gives a total-cost worksheet, how to read safety ratings, the official checks for a used car in Great Britain, and what to look for if you also want to use the car for your test.
Key facts
- Get an insurance quote on the exact car before you buy it. Model, engine size, trim and modifications all change the price.
- GB vehicle tax (as shown on GOV.UK, November 2026): the standard rate for most cars registered from 1 April 2017 is £200 a year, plus an extra £440 a year for five years on cars with a list price over £40,000 (petrol or diesel) or £50,000 (electric). Older cars are taxed on different bands.
- MOT history is free to check on GOV.UK with just the number plate: results, recorded mileage, failed parts and minor problems.
- A star rating belongs to a model and test year, not to the individual car you are looking at.
Step 1: decide what the car is for
Write down the answers before you browse adverts:
- Where will you mostly drive: town, motorway, rural lanes?
- How many miles a year, roughly?
- Will you carry passengers often? (See carrying passengers after passing.)
- Do you hold, or are you taking, an automatic-only licence? If you pass in an automatic, you can only drive automatics. See automatic or manual.
- Where will it be parked, and can you charge at home if it is electric?
- Do you want to practise and take your test in it?
Then sit in the car. Can you get a good driving position, see out well and reach the controls comfortably? A car that suits your body is safer than one that suits a review.
Step 2: work out the total cost for a year
Use this worksheet for each car you are considering. Fill it with real quotes, not guesses.
| Cost | Where to get the figure | Notes |
|---|---|---|
| Purchase price | The advert, after any haggling | Include any finance interest if you borrow |
| Insurance | Quotes on the exact registration | Usually the biggest yearly cost for new drivers. See why insurance costs so much. |
| Vehicle tax | GOV.UK vehicle tax rates (GB); motor tax rules (Ireland) | In GB, check whether the expensive car supplement applies |
| Fuel or charging | Your yearly miles divided by realistic fuel economy | Compare home and public charging prices if electric |
| MOT (GB) or NCT (Ireland) | Official test fees | Budget for repairs the test may reveal |
| Servicing | Quotes from garages | Check the service history for what is due |
| Tyres | Price of the size on the car | Bigger alloy wheels often mean dearer tyres |
| Repairs fund | Your own estimate | Older cars need a bigger buffer |
| Breakdown cover, parking, road charges | Providers, your council, charge schemes | See ULEZ, clean air zones and Dart Charge |
Add it up and divide by 12. That monthly figure is what the car really costs you.
Step 3: check the safety rating properly
Euro NCAP rates new cars sold in Europe, including the UK and Ireland. Its assessment covers areas including crash protection, child safety, pedestrian and cyclist safety and active safety technology. Three points matter when you compare:
- The test year. Euro NCAP says its requirements are updated every three years and its assessment has evolved since the first ratings in 1997. Five stars from many years ago is not the same as five stars from a recent test.
- The exact version. Euro NCAP sometimes gives a second rating for cars fitted with an optional safety pack. Check that the car in front of you actually has that equipment.
- The individual car. A rating says nothing about whether this car has been crashed, badly repaired or poorly maintained. That is what the checks below are for.
If the car has driver assistance features, learn what they do and do not do. See driver assistance systems explained.
Step 4: official checks on a used car in Great Britain
GOV.UK’s used vehicle checklist covers:
- Vehicle details: use the DVLA vehicle enquiry service to check the make, colour, tax status and MOT expiry match what the seller told you.
- MOT history: with the number plate you can see past results, the mileage at each test, which parts failed and any minor problems (for tests in England, Scotland and Wales). It can also show some safety recalls. Mileage that goes down between tests is a warning sign.
- The V5C log book: check it has a ‘DVL’ watermark and that the details, vehicle identification number (VIN) and engine number match the car. Be wary of a seller who says they do not have the V5C.
- A private history check: GOV.UK’s guide to written-off vehicles suggests one to find out if a car is stolen, has outstanding finance, has a mileage discrepancy or has been written off.
- Written-off cars: speak to your insurer before buying one. The premium may be much higher.
Then have the car inspected, or take someone who knows cars, and test drive it. For the paperwork you need once it is yours, see car documents: MOT, tax, insurance and the V5C.
Northern Ireland and Ireland
- Northern Ireland: MOT tests are carried out at DVA test centres, and the GOV.UK MOT history service includes Northern Ireland tests from 2017. See MOT in Northern Ireland.
- Ireland: check the NCT certificate, motor tax and insurance position before buying. See tax, insurance and the NCT.
Step 5: if you want to take your test in it (GB)
Not every car is accepted for the GB driving test. GOV.UK says the car must, among other things:
- be taxed, roadworthy, insured for a driving test and have a current MOT if over 3 years old
- have no warning lights showing safety issues and no tyre damage, with legal tread on every tyre (no space-saver spare)
- have a passenger seat belt and a proper passenger head restraint (not slip-on)
- have an officially fitted mph speedometer and be able to reach at least 62mph
- have an extra interior rear-view mirror fitted for the examiner during the test
- have 4 wheels and a maximum authorised mass of no more than 3,500kg.
Some cars cannot be used because the examiner does not get all-round vision. GOV.UK lists panel vans and models including some convertibles, the 2-door Smart Fortwo, the Toyota iQ and the Polestar 4 and 5, and says other models may be unsuitable too. Check with the test centre before buying a coupe or convertible for your test. For Ireland, see your car for the Irish driving test.
Mistakes first-car buyers make
| Mistake | Better approach |
|---|---|
| Falling for a car, then getting an insurance quote | Quote first, view second |
| Comparing star counts only | Compare test year, version and equipment |
| Trusting the seller’s history | Check MOT history and the V5C yourself |
| Buying with modifications | Modifications usually need declaring and can raise premiums. See modifying your first car. |
| Fronting (insuring it in a parent’s name when you are the main driver) | Insure it honestly, with the real main driver named; ask the insurer if unsure |
| Buying cheap cover from an unknown broker | Check the insurer is genuine. See ghost brokers. |
Common questions
What is the cheapest type of car to insure for a new driver?
There is no single answer. Smaller engines and lower-powered, unmodified cars tend to be cheaper, but the only reliable way to know is to get quotes on the exact cars you are considering.
Should my first car be electric?
It can be, if you can charge cheaply and the insurance quote works. Remember that electric cars have two pedals, so if you learn and pass in one you get an automatic-only licence.
Is a newer car always safer?
Newer designs are generally tested to tougher standards, but condition matters too. A well-maintained car with a good recent rating beats a newer one that has been badly repaired.
Do I need an MOT on a car I have just bought?
In GB, a car needs a current MOT once it is over 3 years old. Check the expiry date on the MOT history service before you buy.
Can I drive my new car home as a learner?
Only with L plates, insurance that covers you as a learner, and a qualifying supervisor. See learner driver insurance in Great Britain and supervising a learner driver.
