How Much is my Car Worth?
A car’s value is influenced by a range of factors, from its age and mileage to its condition and legal status. Understanding how these elements affect pricing helps you interpret valuations realistically and make informed decisions.
This guide explains the key factors that influence a car’s value and how they’re typically assessed.

MOT and Road Tax
A valid MOT can improve buyer confidence, particularly if it has several months remaining. While an MOT doesn’t guarantee a higher value, vehicles without one may be valued lower due to uncertainty or expected repair costs.
Vehicle tax is no longer transferable when ownership changes. While this doesn’t directly affect valuation, it’s an administrative factor buyers are aware of when comparing vehicles.
Many buyers and valuation tools assess vehicles regardless of MOT or tax status, but these details can still influence final offers.
Vehicle condition, appearance, and interiors
Condition is one of the most important valuation factors.
This includes:
-
Exterior bodywork
-
Interior wear and cleanliness
-
Signs of damage or neglect
Cosmetic condition affects first impressions, especially when selling privately. However, expensive cosmetic repairs don’t always increase value enough to justify their cost.
Valuation tools usually assume average condition for a car’s age and mileage unless stated otherwise.
Vehicle age
Age contributes to depreciation, but it’s rarely assessed in isolation.
Newer cars typically lose value more quickly, while older cars depreciate more slowly. Age is usually considered alongside mileage, condition, and demand.
For a deeper explanation of how age compares to mileage in pricing, our guide on whether mileage or age matters more in car valuation explains how these factors interact.
Mileage
Mileage remains one of the strongest value indicators.
Lower mileage often supports higher value, particularly on newer vehicles. Higher mileage can reduce demand, but it doesn’t automatically make a car low value — especially if condition and maintenance are strong.
Mileage is always assessed in context rather than as a standalone figure.
Interpreting your valuation realistically
Car valuations are estimates based on current market conditions, comparable vehicles, and buyer behaviour at a specific point in time.
Understanding how different factors are weighted helps you:
-
Set realistic expectations
-
Compare valuation results
-
Decide when to sell
If you’re considering your next step, getting an up-to-date valuation can help you decide whether it makes sense to sell my car now or review your options.
Key takeaway
A car’s value is shaped by multiple factors working together — not just age or mileage alone. Understanding how condition, legal status, and market context affect pricing helps you interpret valuations accurately and make informed decisions.
