Recently, one of our social media videos sparked a lot of discussion. The video looked at which cars are less likely to make it to 100,000 miles, and the comments quickly filled up with opinions, experiences and stories from drivers who’ve owned cars well beyond that milestone.

What the conversation really highlighted is this. While the car you drive does matter, how you look after it matters even more.

At DCM Autocentres, we see vehicles every day that are still running brilliantly at high mileage, and others that struggle far earlier than they should. The difference usually comes down to maintenance, driving habits and acting early when something doesn’t feel right.

Stick to regular servicing

Regular servicing is one of the biggest factors in how long a car lasts. Oil changes, filter replacements and routine inspections keep everything working as it should and help prevent wear from building up unnoticed.

Skipping services might save money in the short term, but it often leads to bigger, more expensive problems later. Cars that are serviced consistently tend to run smoother, more efficiently and for far longer.

Don’t ignore small warning signs

Strange noises, warning lights, vibrations or changes in how the car drives are rarely nothing. These are often early signs of wear or minor faults that are much easier to fix when caught early.

Many of the major repairs we see started as small issues that were put off. If something feels off, it’s always better to check it sooner rather than later.

Look after your tyres

Tyres play a huge role in how a car feels, handles and wears over time. Incorrect tyre pressures, uneven wear or damaged tyres put extra strain on suspension, steering and braking components.

Keeping tyres properly inflated, replacing them when needed and addressing alignment issues helps protect other parts of the car and improves overall reliability.

Drive with a bit of mechanical sympathy

How you drive has a big impact on longevity. Hard acceleration on a cold engine, aggressive braking and constantly revving the engine all increase wear.

Letting the engine warm gently, driving smoothly and avoiding harsh inputs where possible helps reduce long-term strain on key components.

Be mindful of short journeys

Short trips are harder on cars than many people realise. Engines don’t always reach proper operating temperature, which leads to increased wear and battery drain, especially in colder months.

If most of your driving is short journeys, regular checks and maintenance become even more important to offset that extra strain.

Keep fluids topped up and in good condition

Oil, coolant, brake fluid and screenwash all play important roles. Low or old fluids can cause unnecessary wear, overheating or braking issues.

Simple checks between services can go a long way in keeping things running smoothly.

Don’t put off diagnostics

Modern cars are packed with sensors and electronics. When something isn’t right, diagnostic checks can quickly identify the cause instead of relying on guesswork.

Catching faults early often prevents them from affecting other systems, which helps extend the life of the vehicle.

---

Mileage isn’t the enemy

High mileage doesn’t automatically mean a car is on its last legs. We regularly see well-maintained vehicles with 150,000 miles or more still driving reliably.

It’s usually neglect, not mileage itself, that shortens a car’s lifespan.

A car that’s looked after will usually look after you

That discussion showed there’s no single answer to how long a car will last. What really makes the difference is care, consistency and paying attention.

If you want to get the most out of your car, regular maintenance and early action are always the best investment. Whether your goal is reaching 100,000 miles or going well beyond it, small habits and sensible checks make a big difference over time.

If you ever have questions about how your car is coping or want advice on keeping it running at its best, it’s always worth asking.
