Long-Term Ownership and Reliability

The Toyota Avanza is cheap to buy and maintain compared with larger MPVs. Its 1.3 and 1.5 litre petrol engines are reliable if serviced on time, but high-mileage models often need suspension and brake work. CVT gearboxes can be costly to repair if neglected. Rust is also a common concern in older imports.

On average, annual servicing and maintenance costs around £350 to £550, but large jobs such as gearbox repairs or rust treatment can raise expenses significantly.

Final Thoughts

The Toyota Avanza is a practical seven-seater that offers good value for money and Toyota’s reputation for reliability. Common problems include weak suspension, noisy cabins, and rust, but most repairs are affordable compared with larger family vehicles. For UK imports, regular servicing and rust protection are essential to keep long-term costs under control.

Tips for buyers:

  • Review service history for oil and transmission servicing.
  • Test drive for gearbox smoothness and suspension comfort.
  • Inspect bodywork for signs of rust.

Tips for owners:

  • Stick to routine servicing to protect the engine and transmission.
  • Replace brakes and suspension parts before they cause wider issues.
  • Apply rust protection for longer lifespan.
  • Use quality fluids and parts to reduce wear.
