Most Reliable Individual Models
- Toyota Corolla: Petrol or hybrid, both are incredibly reliable.
- Honda Jazz: Simple, practical, and rarely breaks down.

The cheapest car to own isn't the cheapest to buy, it's the one that doesn't break down. Reliability always wins over features in the long run.
Reliability and Running Costs
Reliable cars cost less to run overall. Here's what to consider:
- Servicing costs: Japanese brands tend to have cheaper parts and simpler mechanics.
- Depreciation: Reliable cars hold their value better. Toyota and Lexus depreciate slowly.
- Insurance: Some brands with known faults cost more to insure.
Think about the total cost over 3–5 years, not just the purchase price.
