When buying a used car, mileage is often one of the first things buyers check.
Many people automatically avoid cars with over 100,000 miles on the clock — but high mileage doesn’t always mean high risk.
In many cases, a well-maintained high mileage car can offer excellent value for money.
This guide explains what to look for, what matters more than mileage alone, and how high mileage affects a car’s overall worth.

Does High Mileage Always Mean Problems?
Not necessarily.
Modern cars are built to last much longer than many buyers assume. With proper servicing and maintenance, many vehicles comfortably exceed 150,000 miles.
Mileage should always be considered alongside:
- Service history
- MOT history
- Previous ownership
- Overall condition
- Type of mileage (motorway vs urban driving)
A high mileage car that has been properly maintained can often be a better buy than a lower mileage car that has been neglected.
And for a clearer picture of what high mileage really means when shopping second‑hand, our piece on whether mileage matters when buying a used car explains the signs to look for beyond the odometer.
What to Check Before Buying a High Mileage Car
1. Full Service History
A complete service record is one of the strongest indicators of responsible ownership.
Check:
- Regular servicing intervals
- Major maintenance work completed
- Garage invoices where possible
A well-documented history often matters more than mileage itself.
2. MOT History
Reviewing MOT records helps identify recurring issues.
Look out for:
- Repeated failures
- Long advisory lists
- Signs of unresolved mechanical concerns
Patterns matter more than isolated issues.
3. Professional Inspection
If possible, have the car inspected by a mechanic.
A professional inspection can highlight:
- Hidden wear
- Suspension issues
- Engine concerns
- Signs of expensive upcoming repairs
This can save significant money later.
4. Consider Ex-Company Cars
High mileage ex-company vehicles can sometimes be strong options.
Why?
Long motorway journeys generally cause less wear than frequent short urban trips.
Motorway mileage often means:
- Less clutch wear
- Fewer cold starts
- Reduced suspension strain
5. Don’t Fear Six Figures
Many buyers hesitate once a car passes 100,000 miles.
In reality, mileage alone tells only part of the story.
A carefully maintained 120,000-mile car may offer far better reliability than a neglected 60,000-mile alternative.
6. High Mileage Often Means Better Value
Because many buyers avoid them, high mileage cars are often priced significantly lower.
This creates opportunities to:
- Buy a higher-spec model
- Access better trim levels
- Save money upfront
The savings can often offset future maintenance costs.
How Mileage Affects Value
Mileage is one of the biggest factors used when valuing a car.
Higher mileage usually reduces value because buyers factor in:
- Increased wear
- Higher repair risk
- Shorter remaining lifespan
However, strong maintenance history can soften this impact.
If you’re weighing up whether age or mileage matters more when judging a car’s condition, our guide breaks down how each factor influences value and long‑term reliability.
Key Takeaway
A high mileage car isn’t automatically a bad buy.
What matters most is how well it has been maintained.
Look beyond the odometer and focus on condition, history, and overall care — that’s where the real value lies.
