Choose based on expected driving, condition, maintenance evidence, purchase price and applicable rules—not fuel type alone. For lower or mixed annual use, petrol may be simpler; regular long-distance use may change the calculation.
Compare your real usage
Estimate annual kilometres, typical journey length, passenger/load needs and how long you plan to keep the car.
- Purchase-price difference
- Realistic fuel and service cost
- Condition and service evidence of the exact car
- Insurance, registration and applicable local rules
The individual car matters most
A well-documented vehicle of either fuel type may be a better choice than a poorly maintained alternative. Test drive and inspect the exact car before deciding.
Evidence note
This guide does not claim a fictional inspection or customer case. Original showroom photographs and real case evidence will be added only after the business supplies and approves the source record.
