How to buy the best new car
Shopping for a brand new car 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.
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.
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 or 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 for more detail.
As well as the initial purchase price, remember to factor in ongoing costs such as fuel, , 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.
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.
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.
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.
A car's security may be an important factor in your choice of which car to buy.
Pay particular attention to the security features of 'keyless entry' cars – whereby a chip embedded in the key fob emits a signal to the car, allowing it to be opened and started without needing to use a key.
Keyless entry cars can be at risk of theft from a 'relay attack'. Thieves use a basic piece of electronic equipment – a 'relay box' – to lengthen the signal produced by the key, fooling the car into thinking it's close by when it's not. Thieves can then open and start your car.
Other security issues we've seen with keyless cars include:
- Ignition blocking attacks – where a criminal can jam an ignition and block the signal from your key fob, preventing you from starting your car and driving away.
- Rolljam attacks – your car key emits a digital signature when you press the fob. A criminal then uses basic equipment to capture the signature. This can be used to unlock the car and potentially drive it away.
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 these attacks. For example, the following measures, introduced by some manufacturers, can reduce the risk of a relay attack.
- and (models since 2018), 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're at home.
- and Mercedes (including pre-2018 models) owners can turn off their keys once they’ve locked the car.
- and use ultra-wide-band (UWB) across their entire range. UWB is a technology that can very accurately determine the distance between the key and the car, so the car can’t be tricked by the relay attack.
You may also be able to completely deactivate the car's keyless functionality, either through the car's instrument panel or by asking your dealer.
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.
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 .
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.
