Car maintenance is about preventing problems before they become expensive or unsafe. Regular checks and servicing help keep your vehicle running smoothly and protect its long-term value.
Routine maintenance typically includes:
Servicing and oil changes
Tyres, brakes, and suspension checks
MOT preparation and repairs
Fluid levels and warning lights
Wear-and-tear items
Staying on top of these areas can reduce breakdowns and make your car easier to sell later.
If you’re thinking about selling, our car selling guidance explains how maintenance impacts value.
👉 Take a look at our “car servicing and maintenance basics” guide.
Following the manufacturer’s service schedule helps prevent mechanical issues and reassures future buyers.
Regular upkeep plays a big role in valuation — our car valuation guidance explains what buyers look for.

Ignoring warning lights can lead to larger problems and reduced resale value.
An MOT is a legal requirement and a key indicator of a car’s condition. Preparing properly can reduce failures and unexpected repair costs.
Common MOT-related issues include:
Worn tyres or brakes
Suspension wear
Lighting faults
Emissions problems
If repairs outweigh the car’s value, our scrapping guidance explains your options.
If your car fails its MOT, you still have options depending on the cost and severity of repairs.
Good maintenance doesn’t just improve reliability — it directly affects how buyers and dealers value your car.
Well-maintained cars tend to:
Attract higher offers
Sell faster
Raise fewer inspection concerns
Poor maintenance can reduce value, even if the car still runs.
“Servicing isn’t necessary if the car runs fine.”
Many problems develop quietly and only appear once damage is done.
“Old cars aren’t worth maintaining.”
Basic maintenance can keep older cars reliable and preserve resale or scrap value.
“Minor faults don’t affect value.”
Small issues can signal neglect and lower buyer confidence.
“I should fix everything before selling.”
Some repairs help value, others don’t — it’s about choosing wisely.
If you’re maintaining your car — or deciding whether further repairs are worthwhile — checking its current value can help you make an informed decision.

Most cars need a service every 12 months or 10,000 miles, whichever comes first.
If you drive shorter trips, tow heavy loads, or use your car in extreme temperatures, servicing may be needed more often. Regular servicing helps prevent breakdowns and keeps repair costs low.
You should never ignore the following dashboard lights:
Engine management light (amber or red)
Oil pressure warning
Battery/charging warning
Brake system warning
If a red light appears, stop the car as soon as it’s safe and investigate immediately. Ignoring these can cause expensive engine or electrical damage.
You may need new tyres if:
Tread depth is below 1.6mm (the legal limit)
There are cracks, bulges, or uneven wear
The steering wheel vibrates at speed
Braking distances feel longer
Checking your tyres regularly improves safety and fuel efficiency.
Every driver should check:
Engine oil
Coolant/antifreeze
Brake fluid
Power steering fluid
Windscreen washer fluid
Running low on any of these can cause performance issues, overheating, or even engine failure.
Most car batteries last 3–5 years.
Signs you may need a replacement include:
Slow engine cranking
Dim headlights
Electrical problems
Battery warning light
Needing to jump-start more often
Cold weather also reduces battery capacity.
You can greatly reduce breakdown risk by:
Keeping up with regular servicing
Checking tyre pressures weekly
Maintaining proper fluid levels
Replacing worn belts and hoses
Keeping your battery in good condition
Small checks now can prevent big repair bills later.
Before winter, make sure to check:
Tyre tread and pressures
Antifreeze strength
Battery condition
Wiper blades and screenwash
Heater and demister system
