Vauxhall Cascada.
What to Check Before Buying.

The Vauxhall Cascada is a four-seat convertible that served as an affordable open-top cruiser from 2013 to 2019. Built on the Insignia platform, it offered decent space and a folding metal roof, making it popular with buyers wanting year-round usability. Most examples were used for leisurely driving rather than high mileage, but age-related issues are starting to show. Check carefully for electrical gremlins, roof mechanism faults, and corrosion before committing.

The average used car has 3+ known model faults the seller won't mention.
