UK Car Cost Comparison: New vs Used

What’s the Difference Between New Car vs Old Car?

A new car is a fresh piece from a factory, and you don’t need to worry about its condition and mileage. You also get the newest tech, safer engines, and often lower road tax. It also gives peace of mind with a full manufacturer’s warranty.

A used car tells a different story, where someone has already driven it, maybe just a few thousand miles, maybe far more. No doubt, the prices are lower, but the running cost can be higher. MOTs, repairs, and the odd part replacement soon come into play. Still, if you choose well, you can get plenty of car for far less money than its brand-new equivalent.

In short, a brand new mode gives you certainty and the comfort of being the first owner, while an older one keeps more cash in your pocket with risks.

Pros and Cons of Buying a New Car

There are both advantages and disadvantages of buying a new car. No doubt it’s fresh, but still it’s important to weigh the pros and cons when buying a new one.

Advantages of buying a new car

Besides the aesthetic of a new car, there are several more convenient advantages, such as:

a. New Technology: A new car usually has the latest safety features and gadgets like, lane assist, better fuel efficiency, and touchscreen infotainment. Older cars just don’t have these things.

b. Warranty Coverage: Most new cars come with a warranty for a few years. If something big goes wrong, the garage sorts it. It’s a nice feeling not having to worry about surprise bills.

c. More Finance Options: Dealers love offering finance deals on new cars. You can get PCP, lease, or low-interest loans that make payments easier. It doesn’t mean it’s cheap, but it spreads the cost out.

Disadvantages of buying a new car

Weighing the disadvantages of buying a new car plays an important role in the decision-making process. 

a. Steeper Depreciation: The moment you drive a new car off the forecourt, it loses value. Big chunks of it in the first three years. Even careful owners can’t avoid it.

b. Higher Upfront Cost: New cars cost more than used ones, plain and simple. Your deposit and monthly payments will be higher, even with finance deals.

c. Potential Higher Insurance Premiums: Insurance tends to be higher for brand-new cars. They cost more to fix or replace, so your insurer charges extra.

Pros and Cons of Buying a Used Car

Buying a used car can be a clever way to stretch your budget. You get more car for your money, but it’s not all smooth sailing. There are a few things to keep in mind before you decide.

Advantages of buying a used car

There are several advantages to buying a used car, and here are such you need to consider:

a. Lower Purchase Cost: Used cars usually cost far less than new ones. You might even be able to afford a model with more features than you’d get new. It’s an easy way to save some cash upfront.

b. Slower Depreciation: The biggest hit on value has already happened. A three-year-old car won’t drop as much in the next few years. You’re less likely to feel that sudden financial sting.

c. Wider Choice in Budget Range: There are loads of used cars out there where you can buy any car within the budget, like hatchbacks, SUVs, even sporty models. You just need good research for the right one. For a tight budget, it gives you options you wouldn’t get buying new.

Disadvantages of buying a used car

Weighing the disadvantages of buying a used car plays an important role in the decision-making process. 

a. Out-of-Warranty Risks: A lot of used cars are past their warranty. If something breaks, it’s down to you to fix it. Sometimes it works out fine, other times it can be a bit of a gamble.

b. Higher Maintenance Costs: Older cars need more attention. Brakes, tyres, and regular servicing can add up, especially if the previous owner didn’t keep on top of things. Sometimes used car does not meet MOT standards. 

c. Limited Choices: You can’t always get the colour or trim you really want. You might have to compromise or wait a while until the perfect car comes in the used market.

Key Factors to Consider Before Deciding

Picking between a new car and a used one isn’t just about the sticker price. There’s more to it than that, honestly. You want something that fits your wallet, your lifestyle, and doesn’t give you headaches later.

Money and Budget
New cars cost a lot, but used cars are cheaper. However, sometimes that saving disappears if repairs pop up. You have to weigh what feels comfortable to spend now versus later.

Depreciation
How much do new cars drop in value the moment you drive them off the lot? That’s the big one. Used cars have already taken the hit, so selling them later is less painful.

Insurance
Insurance can be a nasty surprise. Brand-new cars usually cost more to insure, while older cars are often cheaper, though not always. It’s worth getting a few quotes before deciding.

Running Costs
Fuel, tyres, servicing, it all adds up. New cars need less maintenance comparable to older ones. You’ve got to think long term, not just about the price tag.

MOT and Emissions
If the car is over three years old, it needs an MOT every year. Some older diesels could also get hit by ULEZ charges. New cars usually dodge these problems, at least for a while.

Finance Options
Dealers love offering deals on new cars, including PCP, lease, and low-interest loan options. With used cars, not so much. You may need to plan differently.

Frequently Asked Questions

When will a new car need its first MOT?

In the UK, a new car doesn’t need an MOT until it turns three. That means you’ve got a couple of years of driving before you have to book one. After three years, you have to get an MOT certificate; otherwise, you face a penalty.

What mileage is good for a used car?

There is no specific number, but in the UK the average car drown in a year is 7400 miles. If a car had done much more, it would be considered “high mileage”. But what matters the most is how it’s been cared for. A well-serviced car is still a perfect option to consider.  

How to tax a new car?

You’ll need the 12-digit number from the V5C new keeper slip. Then you can tax it online, which is the easiest way. Post Offices still handle it if you prefer doing it in person. You should make sure you have the right documents. It’s not complicated, but simple can be done easily.

Can you lease a used car?

Yes, you can lease a pre-owned car. Some people call them “re-leased” or “approved used” cars. Payments are often lower than leasing a new car, which is nice. The choice is smaller, though, and the deals vary a lot. 

What is the cheapest new car in the UK?

Right now, the Citroen Ami is the cheapest new car, starting around £7,700. It’s tiny, electric, and mainly for city driving. Other cheap options include the Dacia Sandero and Dacia Spring, both under £15,000. They’re simple, practical, and surprisingly roomy for the price. If you’re looking to spend as little as possible, these are the ones to check.

Final Thoughts: Buying a Used Car vs a New Car

It is not that simple to choose between a new and a used car. There are different factors, like budget, lifestyle and value for money. New cars give peace of mind with the latest features and fewer worries, but they cost more. While used cars are easier on the wallet, but may need more maintenance.
