Introduction: The Challenge of Buying a Used Car
Buying a used car represents an economically advantageous choice for many drivers, but it also hides potential pitfalls. How can you distinguish a genuine bargain from an expensive mistake? The answer lies in the vehicle’s usage data, valuable information that tells the true story of the car you’re about to purchase.
In this article, we’ll explore how to correctly analyze usage data to make an informed purchase, save money, and avoid unpleasant surprises.
Why Usage Data is Fundamental in Evaluation
When evaluating a used car, mileage is just the tip of the iceberg. True experts know it’s necessary to go beyond:
- The previous owner’s driving style can have a significant impact on the durability of critical components
- Actual fuel consumption reveals the engine’s health and can forecast future problems
- Frequency and type of maintenance determine the remaining life of many components
- Refueling history can highlight anomalies in fuel consumption
These data tell much more than a simple visual inspection or a brief test drive ever could.
Essential Data to Verify Before Purchase
1. Mileage and Its Distribution
Don’t just look at the number on the odometer. Ask for information about the distribution of miles:
- How many were driven on highways versus urban routes?
- Were the miles accumulated gradually or intensively in short periods?
- Were there long periods when the car wasn’t used?
A car with 62,000 miles primarily driven on highways might be in better condition than one with 31,000 miles exclusively driven in urban settings.
2. Fuel Consumption
Real consumption is a reliable indicator of the engine’s condition:
- A progressive increase in consumption might indicate fuel system problems
- Irregular consumption might signal electronic or injection issues
- The difference between declared and actual consumption can reveal how the vehicle has been maintained
3. Maintenance History
A car with a detailed and regular maintenance history is generally more reliable:
- Verify that all scheduled service appointments were carried out
- Check if wear-prone components have been replaced (brakes, clutch, timing belt)
- Look for signs of repeated repairs of the same component, which might indicate chronic problems
4. Previous Management Costs
Costs incurred by the previous owner can anticipate your future expenses:
- Extraordinary maintenance costs
- Expenses for inspections and checks
- Fuel costs in relation to miles driven
How to Collect This Data Effectively
Obtaining reliable information isn’t always easy. Here are some strategies:
- Request the complete maintenance booklet with garage stamps
- Verify invoices and receipts for repairs and servicing
- Check the vehicle’s historical report using the chassis number
- Talk to the mechanic who serviced the car, if possible
- Use monitoring apps to verify the consistency of the provided data

- Frequent repairs of the same component
- Increasing maintenance costs in recent months/years
Questions to Ask the Seller About Usage Data
Prepare a list of specific questions:
- Can you show me the actual consumption data from recent months?
- What type of routes has the car primarily driven?
- Has it ever had recurring problems with any component?
- How have maintenance costs changed over time?
- Have you used an app to keep track of this data?
