10 Tips for Buying a Used Car in 2026
Successfully Finding Your Dream Car
Buying a used car requires preparation. With these 10 tips based on our market analysis of over 2,000 vehicles, you’ll maximize your chances of getting a good deal.
1. Choose the Right Time
January and November-December are the best buying months according to our seasonal analysis:
- Lower demand after holidays
- Dealers want to meet year-end targets
- More room for negotiation
Avoid: Spring (March-May) when demand is highest.
2. Properly Assess Mileage
Our data shows: The importance of mileage varies significantly:
| Vehicle Type | km/Price Correlation | What This Means |
|---|---|---|
| Newer models (C6, C7) | strong (-0.9) | Every km counts |
| Classics (E38, B5) | weak | Condition matters more |
| Performance (M3, RS4) | medium | Both matter |
Tip: For vehicles over 15 years old, documented condition is often more important than mileage.
3. Know Market Prices
Research on our model pages before visiting dealers:
- Average price as negotiation baseline
- Minimum and maximum for realistic expectations
- Price trend for timing decisions
4. Insist on Service History
Especially with German premium brands, maintenance determines longevity:
BMW: Inspections in data storage, oil change intervals Mercedes: Service book, digital maintenance log Audi: Service book, timing belt/chain replacement proof
5. Know Typical Weak Points
BMW E38/E39/E46:
- Cooling system (water pump, thermostat, expansion tank)
- Vanos seals on 6-cylinders
- Suspension rubber bushings
Mercedes W140/W210:
- Airmatic suspension (if equipped)
- Rust on wheel arches and sills
- Electronics aging
Audi B5/C6:
- Turbocharger on biturbo models
- Timing chain on 2.0 TFSI (C6)
- Avoid CVT transmissions
6. Conduct Test Drives Properly
At least 30 minutes, test all driving situations:
- Cold start and warm-up
- City, country road, highway
- Hill driving for transmission/clutch
- Emergency braking (safe location)
What to watch for:
- Noises during cold start
- Shifting behavior warm vs. cold
- Vibrations at different speeds
7. Negotiate with Facts
Use our data as negotiation foundation:
“The average market price for this model is €X. This vehicle has above-average mileage, so I’m proposing €Y.”
Effective arguments:
- Pending repairs
- Missing service records
- Deviation from market price
- Seasonal factors (winter purchase)
8. Calculate Financing
Calculate all costs before buying:
Running costs for German premium:
- Insurance: €800-2,000/year
- Maintenance: €500-1,500/year
- Fuel: depends on engine
- Wear parts: tires, brakes
Repair reserves: 10-15% of vehicle value per year recommended.
9. Check Vehicle History
Essential before buying:
- Inspection reports from recent years
- Confirm accident-free status
- Number of previous owners
- Request MOT report
Online check:
- Mileage plausibility
- Don’t pay deposits in advance
- For private purchases: contract with all details
10. Dealer vs. Private
| Aspect | Dealer | Private |
|---|---|---|
| Price | +10-20% | Cheaper |
| Warranty | 1 year mandatory | None |
| Return rights | Sometimes | No |
| Financing | Possible | Rarely |
Recommendation: For classics over 20 years, often better examples at specialized dealers or enthusiast private sellers.
