The SEAT Arona is a small crossover launched in 2017 on the MQB A0 platform — shared with the VW T-Cross, Skoda Kamiq and Audi A1. It competes with the Nissan Juke, Renault Captur and Ford Puma. No diesel option is available from the MK2 refresh. Known for its colourful styling, strong value and competitive pricing against German rivals. Being a relatively newer model, significant faults are still emerging as cars age.
