Top 10 Tips for Buying a Used Car

Buying a used car can be a challenge

For most people, finding and buying a used car is a pain. It takes way too much time and, in the end, how can you be sure that you got a good car at the right price?

It’s a large purchase and one where the experience and information is usually on the side of the dealer selling the car. There are some great car dealers ready to be helpful but there are also some very poor one who only want your money… and will do anything to get it.

At Palmdale Car Finders, we’ve spent two decades helping thousands of UK car buyers navigate the process. We’ve learned what works (often the hard way). So, here are our 10 tips to help you find the perfect used car.

1. SET A BUDGET (AND STICK TO IT)

The biggest mistake many buyers make when choosing a used car is not setting a clear budget before starting their search. Work out:

Once you have your budget, stick to it! Car dealers are experts at upselling, so knowing your limit will prevent you from being pressured into overspending.

2. BE VERY CLEAR ABOUT WHAT YOU WANT

Buying a car without a plan is like going food shopping when you’re hungry — you’ll end up with things you don’t need. Before you even open AutoTrader, decide on the following:

Knowing your priorities will keep you focused and prevent you from getting talked into buying something that doesn’t suit your lifestyle.

3. RESEARCH ONLINE FOR RELIABILITY AND VALUE OF SPECIFIC MODELS

Not all brands and models are created equal when it comes to reliability and long-term value. Here’s a quick summary of what to expect:

Remember that after that warranty expires, you’ll have to pay for any repairs needed.

Will you go for a less-exciting Hyundai, Kia or Toyota because they last well. Or does your budget stretch to a quality BMW, Audi or Mercedes which should work well but will be pricey if any work is needed. Perhaps you only want a Land Rover – as lovely as they are, they’re notorious for reliability issues.

Do your research on common faults, recalls, and running costs. What looks like a bargain might turn out to be a money pit.

4. SEARCH SMARTLY AND WIDELY

The key to getting the best deal is to cast a wide net. The best platforms for UK car buyers are:

AutoTrader – The biggest used car site in the UK.

eBay Motors – Great for finding private sellers and the occasional bargain.

Facebook Marketplace – Hit or miss, but potential for cheap finds.

Manufacturer websites – Approved used cars often come with extra warranties.

Top Tip: For AutoTrader, use a website browser extension like Motorwatch or AT Price Tracker to see when an advert was listed and if the price has dropped.

5. WATCH OUT FOR WRITE OFFS (‘CAT’ CARS)

If you see terms like CAT S, CAT N, or similar in an advert for a used car — proceed with caution. These are cars that have been written off by insurance companies and repaired. While they’re cheaper, the hidden damage can create long-term issues.

CAT S – Structural damage (e.g., chassis damage)

CAT N – Non-structural damage (e.g., cosmetic or electrical issues)

Unless you know exactly what you’re doing, avoid CAT cars.

6. ASK THE RIGHT QUESTIONS BEFORE VIEWING

Before you even travel to see the car, get as much information over the phone as possible. Key questions include:

How the seller answers these questions can tell you as much about the car as the answers themselves.

7. DON’T SKIP THE INSPECTION

Once you’ve found a promising car, don’t just take the seller’s word for it — inspect it thoroughly:

Bodywork – Look for uneven panel gaps and mismatched paint.

Tyres – Minimum tread depth is 1.6mm — ideally you want 3mm or more.

Interior – Check every button, switch, and system (including A/C and infotainment).

Engine Bay – No leaks, no rattles, no smoke.

Test Drive – Listen for noises, test the clutch, and try emergency braking.

If you’re not confident inspecting a car yourself, consider hiring a professional to give it a once-over.

Remember that if you’re buying a car as a business, you won’t have the same consumer rights as an individual.

8. GET THE PAPERWORK RIGHT

Make sure the car comes with:

Double-check that the registration number, VIN, and other details match. If anything seems off — walk away.

9. NEGOTIATE LIKE A PRO

Some car dealers work strictly on fixed prices, but it is always worth asking if there is any discount available. Follow these rules:

Here’s an example line:

“If we can agree a sale today, how much could I buy the car for?”

10. UNDERSTAND YOUR LEGAL RIGHTS

If you’re a private buyer purchasing a car from a dealer, you have legal protection under the Consumer Rights Act 2015. If the car develops a fault within the first six months, the dealer is obligated to fix it or offer a refund.

And there are further rights should the fault be major, occur within the first 30 days or repeat itself. It’s far easier to reject a car than most people realise.

If the dealer refuses, you can escalate the issue with Trading Standards.
