Toyota Duet: The Daihatsu Storia and Sirion cousin, what to know before buying
Toyota Duet — a compact hatchback that Daihatsu produced from 1998 to 2005 and sold in Japan under the Toyota badge. The same car was known as the Daihatsu Storia or first-generation Sirion in other markets. We look at what makes it special and what to check before buying.
Duet in brief
The Duet is a compact five-door hatchback with front-wheel drive or all-wheel drive. The base model was the Daihatsu Storia, which replaced the Charade. In Japan, it wore the Toyota badge and replaced the Corolla II.
In most other countries, except for a few, the same car was sold as the first-generation Daihatsu Sirion. Therefore, finding parts and information about it is easier than it seems.
Versions — what sets them apart
The Duet existed in one generation (1998–2005). Versions differed in trim and equipment, for example, 1.0V and 1.0X.
The main difference between the Duet and the Storia or Sirion is the badge and the market. In Europe, the Sirion is most commonly encountered.
Engines and transmissions
The main engine is a 1.0-litre three-cylinder petrol unit. Export Sirion versions also offered a larger 1.3-litre four-cylinder engine.
Transmissions come in manual or automatic. Some models featured all-wheel drive.
These are simple, economical engines, but with modest power, making the car best suited to urban driving.
What to check when buying a Duet
Inspect the body for rust, especially the sills, wheel arches, and rear wheel arches. Ask for the service history.
Check that the engine has no oil leaks and that the distribution mechanism has been serviced on time, and that the automatic gearbox shifts smoothly.
If the car has been imported from Japan, check the documents and condition against the auction sheet, and ensure it meets European requirements.
