Frequently asked questions

Is the ETG gearbox a dealbreaker?

It is unpleasant rather than unreliable, but retail buyers notice it, so price accordingly.

Is the Cactus cheap to run?

Yes, it is light, economical and sits in low insurance groups.

What about the Airbumps?

They protect the doors but look tired when faded, which affects presentation.

Which version sells best?

The manual 1.2 PureTech with a documented belt change.

Are the pop-out rear windows a water leak or security risk?

The hinged rear windows rarely suffer from water ingress if the rubber seals are kept clean. However, the plastic latch mechanism can become stiff or snap if forced by passengers. Security is not a major concern, but always ensure both latches operate smoothly and pull the glass tight against the seal.

Does the 2018 facelift model resolve the early first-generation issues?

The 2018 facelift drastically reduced the size of the Airbumps and introduced progressive hydraulic cushion suspension for a softer ride. It also replaced the jerky ETG automated manual with a much smoother EAT6 torque-converter automatic. However, the 1.2 PureTech cambelt architecture and touchscreen-reliant cabin controls remained unchanged.
