Buying a used car can be a smart financial decision—but for first-time buyers or those unfamiliar with the process, it can also be a bit overwhelming. When a brand-new car rolls off the showroom floor, it immediately loses about 20% of its value. This depreciation happens the moment it becomes a “used” vehicle. Add to that taxes and fees, and you could be losing thousands of pounds or dollars instantly.
For this reason, many savvy shoppers turn to the second-hand market. Purchasing a pre-owned car is often far more economical and can provide the same performance and features—if you know what to look for.
To help you navigate the used car buying process, automotive enthusiast and expert Kaan Craig has shared his top five recommendations. Whether you’re browsing online listings or checking out local dealers, these tips will give you the confidence to make a solid, informed decision within your budget.
1. Set a Game Plan Before You Start Searching
Before diving into online ads and dealership websites, take some time to define your needs and budget. Creating a simple checklist can save hours of time later—and potentially prevent costly mistakes.
Key Questions to Ask Yourself:
What is your total budget? Include only the amount you’re willing to spend on the car itself. Additional expenses such as insurance, vehicle registration, fuel, and repairs should be budgeted separately. Experts recommend keeping a reserve of £500–£1000 for any unexpected post-purchase issues.
What do you need from a car? Are you looking for a reliable commuter vehicle, a spacious family car, or a sporty two-seater? Think about size, comfort, fuel efficiency, and driving habits.
What type of fuel suits you? Consider whether you prefer a petrol, diesel, hybrid, or electric vehicle. Each has its own advantages depending on your usage.
Do you have a preferred brand or model? Narrow your focus to 2–3 models you like, but keep an open mind—other vehicles might offer better value.
Check insurance costs in advance. Use online tools to get insurance quotes on the models you’re considering. Sometimes insurance premiums can be surprisingly high for seemingly average cars.
By creating a plan before you begin shopping, you’ll filter out options that don’t meet your needs—and avoid being tempted by flashy models outside your budget.
2. Research Common Issues for Specific Models
No used car is perfect, and every model has its own set of known issues. This is why it’s crucial to research the most common problems for the vehicle you’re considering.
For example, certain engines may be prone to timing chain failures, turbocharger issues, or transmission problems. An Audi S4, for instance, is known for potential timing chain tensioner failure, which can lead to expensive engine repairs costing upwards of £3,000.
What You Should Do:
Look up forums, owner groups, and YouTube reviews for honest insights into the model’s reliability.
Write down a list of common faults for the cars you’re interested in.
Take this list with you when inspecting a vehicle, and use it to guide your questions.
Spotting potential faults early can give you leverage to negotiate the price—or help you walk away from a bad deal before it’s too late.
3. Use Trusted Online Platforms to Find Cars
The internet has made it easier than ever to find a great deal on a used car—but not all platforms are created equal. Some sites are filled with overpriced listings, outdated ads, or even scams.
Best Places to Start Your Search:
Auto Trader – One of the UK’s largest car marketplaces with hundreds of thousands of listings updated daily.
eBay Motors – Ideal for private sellers, with the added benefit of user reviews and seller ratings.
Gumtree – A great place for local deals, though it’s important to be cautious and verify the seller.
Owner Club Forums – Enthusiast communities can offer well-maintained vehicles with detailed service histories.
Facebook Marketplace – A fast-growing place to find local cars, but proceed carefully and meet in safe locations.
Always be cautious of listings that seem “too good to be true,” and don’t hesitate to ask sellers detailed questions about the car’s history, condition, and paperwork.
4. Bring a Knowledgeable Friend and Inspect Thoroughly
Never view a used car alone—especially if you’re unfamiliar with basic mechanical checks. A second pair of eyes can be invaluable during your inspection.
Inspection Tips:
Bring someone with automotive experience. A friend or relative who knows cars can help spot issues you might overlook.
Check the Vehicle Identification Number (VIN). Make sure it matches the number on the logbook (V5C) and is stamped on the car (usually on the dashboard or engine bay).
Start the car when it’s cold. Ask the seller not to start it before your arrival. Cold starts can reveal hidden problems like excessive smoke or rough idling.
Meet at the V5C-registered address. To avoid scams, always view the car at the address listed on the registration document. Ask to see the seller’s ID and confirm it matches.
Test drive the car. Listen for strange noises, check the brakes, and test the clutch (if manual).
If anything feels off or if the seller avoids your questions, don’t feel pressured to proceed. It’s better to walk away than to take on a money pit.
5. Consider Car Rental if You Don’t Drive Often
If all this sounds like too much hassle—or you only drive occasionally—you might be better off renting instead of owning.
Renting Can Be a Cost-Effective Alternative:
Avoid costs like MOTs, annual servicing, tax, and depreciation.
Use comparison sites like Carrentals.co.uk to find cars in your area for as little as £20 per day, including insurance.
Ideal for city dwellers, remote workers, or people who drive less than 5,000 miles per year.
Some drivers even alternate between car clubs and short-term rentals instead of owning a vehicle, saving thousands annually.
Conclusion
Buying a used car online doesn’t have to be risky or stressful—if you go in prepared. By planning your budget, researching common faults, using trusted sites, and inspecting the vehicle carefully, you can drive away with a car that suits both your needs and your wallet.
And if it turns out that car ownership isn’t worth the cost or commitment, renting remains a flexible and budget-friendly option.
