Notes: The table presents only verified data available from the supplied vehicle information. Several specifications commonly requested by buyers are not available in the supplied data and are marked accordingly. Always confirm missing details on the specific vehicle listing or factory documentation before purchasing.

Engine and Performance

Verified fact: the LA400K Robe S uses a 658 cc engine, consistent with Japanese kei-class regulations. The drivetrain is front-wheel drive (FF). Other specific performance figures such as horsepower, torque, and transmission type for this exact Robe S example were not available in the supplied data and should be confirmed from the seller or official spec sheet.

Driving impressions (general): As a kei convertible with a sub-700 cc engine, expect modest straight-line performance suitable for city driving and short touring rather than high-speed highway cruising. The Copen’s light weight (870 kg listed) supports responsive low-speed handling and nimble maneuvering in urban conditions. For precise acceleration, top speed, and transmission behaviour, verify the exact outputs on the vehicle’s documentation.

Exterior Design and Dimensions

The Copen’s compact footprint is one of its main selling points. The verified external dimensions are 3,395 mm long, 1,475 mm wide and 1,280 mm tall. These dimensions make the Copen highly maneuverable and easy to park in tight Japanese and urban international environments.

The Robe S trim typically carries unique styling cues and a higher level of visible trim over base models; however, verified details of exterior equipment and optional packages for this Robe S example were not included in the supplied data. If exterior condition and corrosion are concerns for import buyers, ask for high-resolution photos of the roof mechanism, underside, wheel arches and door sills before bidding.

Interior, Comfort and Technology

Specific interior features, seating capacity and infotainment options for the LA400K Robe S were not available in the supplied vehicle data. The Copen line is commonly a compact two-seater with a focus on driver-centric layout, but seating and equipment must be confirmed for each listing. Buyers should request a full option list and clear interior photos that show dashboard, seats, infotainment, and trim condition.

Safety equipment (airbags, stability control, etc.) and convenience features (cruise control, navigation, heated seats) are often trim-dependent. Because the supplied data does not verify these features for the Robe S shown, confirm the exact specification with the seller or auction sheet.

Fuel Economy and Everyday Practicality

Official fuel economy figures (JC08 or WLTC) were not provided in the supplied data. Typically, kei-class 658 cc engines deliver excellent urban fuel economy, but the specific JC08 or WLTC figures for the Robe S LA400K must be checked on the official spec sheet or vehicle listing.

Practicality wise, the Copen’s compact size makes it ideal for city parking and short commutes. Considerations for international buyers include limited luggage space, roof mechanism condition (for convertibles), and the suitability of a small-displacement engine for longer highway trips depending on your local road speeds.

Is the Daihatsu Copen Robe S LA400K a Good Used Car to Buy?

The Copen Robe S LA400K can be a great choice if you want a distinctive, compact sporty convertible with JDM charm. Strengths often include unique styling, easy urban usability, and efficient running costs typical of kei-class cars. Limitations include the small engine displacement, likely limited cargo space, and lower practicality for long interstate driving.

Before buying or importing:

• Verify all technical specs missing from the listing (power, torque, transmission, seating).
• Inspect the convertible roof mechanism and seals.
• Check for body damage, rust, and accident history.
• Confirm what safety and convenience features the specific car has.
• Factor import costs, compliance modifications, and local registration rules.
