3. Read owner forums: Real owners share known faults and reliability experiences.

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.
