Thinking about buying a used diesel car? You've come to the right place. Diesel cars have long been a favourite for drivers who cover a lot of miles, thanks to their impressive fuel economy and strong performance. While the conversation around diesel has changed, a modern used diesel car can still be a brilliant, cost-effective choice.
This guide will walk you through everything you need to know, from the benefits of choosing a diesel engine to the key things to check before you buy. We'll help you find the perfect second-hand diesel car for your lifestyle.
Why Buy a Used Diesel Car?
Choosing a used diesel car offers some fantastic advantages, especially if you spend a lot of time on motorways. Imagine cruising on a long journey, watching your fuel gauge barely move. That’s the magic of diesel efficiency. They often provide more pulling power (torque) at low revs, which is great for towing or simply enjoying a relaxed drive.
Buying a used diesel means you get all that performance and economy at a much lower price point than a brand-new model. It’s a smart way to get a high-spec vehicle without the steep initial cost, making your money go further.
What to Look for When Buying
Finding a great used diesel car is all about knowing what to check. A little homework can save you a lot of hassle down the road. Here’s a simple checklist to follow:
- Service History: A full service history is a must. It shows the car has been well-maintained. Check for regular oil changes and, crucially, that the diesel particulate filter (DPF) has been serviced according to the manufacturer's schedule.
- DPF Condition: The Diesel Particulate Filter can get clogged, especially on cars used only for short, urban trips. Ask about the car's previous usage. A warning light on the dash could signal an expensive problem.
- Test Drive: Take the car for a thorough test drive. Listen for any unusual noises from the engine. Check for black or blue smoke from the exhaust when you accelerate, as this can indicate engine issues.
- Glow Plugs: Diesel engines use glow plugs to help them start in cold weather. If the car struggles to start from cold, the glow plugs might need replacing.
- General Checks: Don't forget the usual checks—tyres, brakes, bodywork, and interior. Make sure everything feels right and works as it should.
