13 Helpful Tips For Buying Or Selling A Car

Whether you’re upgrading to something new or trying to get the best deal on your current car, buying and selling can get a bit murky.

With the rise of electric cars, changing regulations, and more online marketplaces than ever, it’s important to stay ahead of the game — and ensure you’re not getting ripped off. These tips will help you navigate the process smoothly while ensuring you get the best value for your money.

1. Research the market before making any moves.

Before buying or selling, take the time to understand current market trends. Car prices can fluctuate due to supply chain issues, fuel prices, and the increasing demand for electric vehicles. What was a fair price six months ago might not be realistic now. Use platforms like AutoTrader, eBay Motors, and Facebook Marketplace to compare prices on similar models. Pay attention to factors like mileage, condition, and location to get an accurate idea of what your car is worth or how much you should expect to pay.

2. Consider the shift towards electric and hybrid cars.

With new regulations pushing for cleaner vehicles, the market for electric and hybrid cars is growing rapidly. If you’re buying, consider whether an EV or hybrid would suit your lifestyle, especially with more charging infrastructure rolling out across the UK. Many cities are also introducing low-emission zones, making petrol and diesel cars less practical. If you’re selling, this shift means petrol and diesel models may take longer to sell or lose value faster. If you own an older car, now might be the best time to sell before demand drops even further.

3. Get a pre-approved loan if you’re financing.

Car finance rates change regularly, and dealerships don’t always offer the best deals. If you’re buying on finance, get a pre-approved loan from a bank or credit union before visiting a dealer. This gives you more bargaining power and prevents you from being pressured into high-interest dealership financing. Having a loan pre-approved also means you know your budget in advance, helping you narrow down your options and avoid overspending.

4. Don’t underestimate the value of a private sale.

Dealerships make selling easy, but they rarely offer the best price for your car. If you want to get the most money, selling privately through online platforms can be worth the extra effort. Websites like AutoTrader and Facebook Marketplace allow you to set your own price and negotiate directly with buyers. Make sure your listing is clear, with high-quality photos and a detailed description. Be prepared for time-wasters and scammers, and always meet in a safe, public place when showing your car.

5. Get a professional valuation before listing your car.

Knowing your car’s exact value helps you set a competitive price and avoid being lowballed. Online tools like WeBuyAnyCar, Parkers, and AutoTrader’s valuation service give you an estimate based on real-time market data. If you’re selling privately, price your car slightly higher than its valuation to leave room for negotiation. If you’re trading it in, use your valuation as leverage to push for a better offer.

6. Check the vehicle history before buying.

Never buy a car without running a full vehicle history check. Services like HPI Check and CarVertical can reveal if a car has been written off, has outstanding finance, or has been stolen. These issues can turn what seems like a bargain into an expensive headache. Even if the seller seems trustworthy, always verify the car’s history yourself. A clean record gives you peace of mind and ensures you’re making a safe investment.

7. Be prepared to negotiate, whether buying or selling.

Negotiation is key to getting the best deal, and most buyers and sellers expect some level of haggling. If you’re buying, start lower than your budget and let the seller counter. If you’re selling, set your asking price slightly above what you’re willing to accept. Research comparable listings beforehand so you can back up your offers with facts. Being polite but firm increases your chances of striking a deal that benefits you.

8. Look out for scams and red flags.

Online car sales have made buying and selling easier, but also increased the risk of scams. Watch out for deals that seem too good to be true, buyers who rush the process, and sellers who avoid answering questions. Never send money before seeing a car in person, and avoid bank transfers to unknown individuals. If something feels off, walk away—there will always be other deals.

9. Get a pre-purchase inspection on second-hand cars.

A car might look great in photos, but underlying issues aren’t always visible. If you’re buying a used car, consider getting an independent mechanic to inspect it before committing. This can reveal hidden problems that could cost you down the line. Most reputable sellers won’t mind an inspection, and if they do, that’s a red flag. Spending a little extra on an inspection now can save you thousands in unexpected repairs later.

10. Understand the impact of mileage and condition on value.

Both buyers and sellers should understand how mileage and condition affect price. Low-mileage cars tend to hold their value better, but a well-maintained higher-mileage car can still be a great buy. Service history, tyre condition, and recent repairs all play a role in pricing. If you’re selling, consider getting small repairs done before listing to make your car more appealing. If you’re buying, check the service history to ensure the car has been looked after properly.

11. Check the latest tax and emission regulations.

New emission rules and tax changes could impact the value of the car you’re buying or selling. Low-emission zones in cities like London mean older diesel vehicles could cost more to run. Road tax is also changing, especially for electric and hybrid cars. Before making a purchase, check how much tax and insurance will cost you annually. If you’re selling, be aware of any upcoming changes that could affect your car’s desirability.

12. Read the fine print on warranties and service plans.

Many modern cars come with extended warranties and prepaid service plans, which can add value for buyers. If you’re selling a car that still has warranty coverage, make sure to highlight that in your listing. If you’re buying, check what’s covered and whether the warranty can be transferred. Understanding these details can help you avoid unexpected repair costs and make a more informed purchase.

13. Timing can make a difference.

The time of year can affect both buying and selling prices. Dealerships often offer discounts at the end of financial quarters, while private sellers may drop prices at the end of the month when they need quick sales. Convertibles sell for more in summer, while 4x4s and SUVs become more desirable in winter. If you’re selling, listing your car at the right time can help you get a better price. If you’re buying, knowing when to shop could save you a decent amount.
