Shopping for a brand new car can – and should – be an enjoyable and exciting experience. It’s your chance to tailor your new car to your exact tastes, choosing everything from the seat fabric to the type of engine and gearbox.

But with thousands of pounds at stake, you want to be sure you’re choosing the right car in the right specification, and getting it for a good price. This guide sets out the five key steps to ensure you do just that.

Want to just start browsing the best cars you can buy? Take a look at all our new car reviews.

In this article:

1. What car should I buy?  

Even if you think you know what kind of car you’d like to buy, it’s still worth considering your requirements. You may find that the car you want and the car you need aren’t quite the same thing.

For example, while you may like the looks or high driving position of a large SUV, all-wheel-drive is rarely necessary in the UK unless you live in a remote rural area or regularly go off-road. 

While you may like the idea of buying a car from a ‘premium’ brand such as BMW or Lexus, you may find you can get all the refinement and features you need from a more mainstream brand – and at a lower price.

We recommend you write a list that prioritises what you want and need a new car to do – and that should include an idea of how much you’re willing (and able) to pay. It's also worth considering where you're going to be spending most of your time driving, to assess whether a hybrid car or electric car could lower your running costs.

How much can you afford to spend?

Cars are expensive – quite likely the most expensive thing you’ll buy aside from a property. So it’s vital you don’t spend over the odds, or over-extend your finances.

Make an honest assessment of your available budget. Bearing in mind that although a finance deal may make a car more affordable in the short-term, paying  up-front is often the cheapest way to buy one in the long run. Read our car finance explained guide for more detail.

As well as the initial purchase price, remember to factor in ongoing costs such as fuel, car tax, car insurance, servicing and depreciation (more on this below). Then compare like-for-like with pay-monthly finance deals, as they may include some of these costs.

All of our expert, impartial car reviews include realistic fuel economy figures taken from our rigorous tests, so you can use these with our petrol vs diesel fuel calculator to work out your annual fuel costs.

2. Do your research 

Once you’ve narrowed down what you need the car to do – and any other criteria, such as looks or brand – it’s time to start researching the most suitable models available in your price range.

A good first step is to read our in-depth new and used car reviews. You can filter these according to starting price, brand, and all sorts of features, from fuel type to car class.

In our reviews, you can also find out if the car you're interested in is likely to last. Thanks to our annual survey of thousands of car owners, we can know which cars are the most - and least - reliable.

3. Draw up a new car shortlist 

Done your homework? Good. Now you can compile your shortlist of cars you’re most interested in. Then your next step is to contact local dealers to book in some test drives.

Some brands offer 24-hour or weekend-long test drives, so don't be fobbed off with a 10-minute spin round the block. A car that looks good on paper won’t be if you can’t easily get in or out of it, or you don’t like the way it feels to drive.

We rate every car we test on how smoothly it drives, how well it accelerates and we run repeat tests of braking from 62mph to standstill. This allows us to see if braking distance is consistent and doesn't increase with repeat runs.

Which means you can use our car reviews to make sure you don't waste your time on a model that will be a pain to drive.

Understanding car depreciation

In simple terms, the longer you keep a car, the less it will be worth if you sold it – and some cars depreciate much faster than others. It's usually unavoidable unless you’re buying a sought-after classic.

Depreciation is a major cost when buying a new car. If, like most people, you’re likely to want a new car before your old one is ready for the scrapyard, try to buy a model that depreciates slowly. 

There is no hard and fast rule about depreciation, but you can help alleviate it if you: 

  • Specify a car in a desirable specification, with choice options 
  • For example, a car in a neutral colour will be easier to sell (and command a higher price) than one in an attention-grabbing hue.

Whichever car you choose, depreciation is likely to account for more than half of your running costs over the first three years. It can affect expensive models from premium brands just as much as a cheap car from a mainstream brand, and the sums involved – the amount you ‘lose’ – can be much higher.  

But it’s irrelevant if you keep your car until it wears out.

Every year, we survey thousands of car owners to find out which cars you can (and can't) depend on - go to the most reliable cars.

Car security

Keyless cars can be at risk of theft from 'relay boxes', which are used to lengthen the signal produced by the key, fooling the car into thinking it's close by. Thieves can then open and start your car.

If a car you're interested comes with keyless entry, or it's bundled in with an option you want, ask the dealer what the manufacturer is doing to combat relay attacks.

BMW and Mercedes, for instance, have added motion sensors into their key fobs. So the key won't produce a signal if it isn't moving - such as when you've at home. 

Mazda lets you get the keyless function deactivated for free.

4. Where to buy your new car and how to finance it 

While you may be more familiar – and comfortable – with the idea of visiting your local dealer to buy a car, it’s now possible to buy a new (or used) model entirely online or over the phone.

There are pros and cons to both buying in-person and remotely, so we recommend you read our guide to where to buy a car to help you decide what’s best for you.

The right way to pay will also depend greatly on your circumstances and the deals on offer at the time of purchase. To learn more about payment and ownership options – leasing (renting) a car is increasingly popular and affordable – take a look at our guide to car finance explained.

Some dealers and brokers sell ‘pre-registered’ cars, which are often attractively priced with discounts of as much as 30%.

Some dealers and brokers sell 'pre-registered' cars. These are often well-priced with discounts of as much as 30%.

However, buying a pre-registered model could mean a shorter warranty – the warranty starts as soon as the car is officially registered, which could be months before you buy the car. You’ll technically be the second owner, as the dealer who registered the car will be the first.

5. Shop around and haggle hard! 

A key advantage of online (or phone) car buying is the ability to compare prices from dealers all over the country without necessarily having to haggle with them yourself. 

Depending on the car-buying service or broker you contact, they will have either pre-negotiated discounts from dealers, or will do it on your behalf once you’ve told them what car you’re after.

Even if you’d rather buy locally, do collect quotes from several sources as prices vary enormously across the country. You may find your local dealer will match or beat a price to secure a sale.

How to haggle

If you are buying in person at a dealer, go well-prepared. 

  • Have a good idea of the exact model, trim level, engine-specification and options you’d like, and how much you should be paying
  • The price you see in the brochure (or stuck to the windscreen) should be viewed as a starting point for a negotiation 
  • The sales team nearly always has some room to manoeuvre on price, so push hard for a discount. 
  • If they don’t offer one (or some sort of other incentive, such as free servicing or desirable optional extras) be prepared to walk away – there’s always another way to buy your perfect new car.

To learn more about haggling, including examples of what to say to maximise your chances of getting a discount, read our expert guide on how to get the best price on a car.

Bestselling cars compared 

We've tested all of the UK's bestselling cars. Below, we've listed the key specs and features for the three most popular models to help you find out whether one is right for you.

Alternatively, head to our round-up of the best cars you can buy.

Ford Fiesta

  • Class: small
  • Price: from around £14,360

The Ford Fiesta is the UK's bestselling car and has been for many years. This small car comes in a wide choice of trims and you get to choose from six engines, so there's something to suit everyone.

Unlike some rival small cars, visibility is ok and you can see traffic around you fairly easily - particularly important if you regularly drive in busy cities.

Its main controls are well laid out and the pedals and gear lever are well positioned.

But how did this car perform in our tough tests and is it reliable? See our Ford Fiesta review.

Volkswagen Golf

  • Class: medium
  • Price: from around £17,420

The Volkswagen Golf has been a driving force on UK roads for decades, and is now in its seventh guise.

You get a wide choice of petrol and diesel engines and the Golf shares many traits with the more expensive Audi A3.

This family hatchback has impressive leg-room up front, with more space than in some people carriers.

But is it economical to run and can you depend on it? Our Volkswagen Golf review reveals all.

Ford Focus

  • Class: medium
  • Price: from around £17,000

A direct rival to the VW Golf, yet a shade cheaper, the latest Focus is laden with tech.

There are nine trim levels to choose from. Even the entry-level Style model is well equipped, and the posh Vignale comes with a B&O sound system.

Like the Golf, you get plenty of room inside and a practical boot. The Focus also comes in both five-door hatchback and estate guises, though all share the same engines and trim line-up.

So how does this car compare to the Golf and do we recommend it? See our Ford Focus review.
