Yes, the Ibiza is a small car in the grand scheme of things, but you might be surprised by how spacious it is in the back – especially considering Seat’s history of prioritising chiselled looks over practicality. There's considerably more leg room than you'll find in the back of a Ford Fiesta or a Skoda Fabia, for example. The only car in the class that offers more is the MPV-shaped Honda Jazz. The Ibiza also has plenty of head room to cater for six-footers.
As with most cars in this class, squeezing three adults in the back makes life a bit uncomfortable for everyone involved. It’s perfectly doable if the journey isn’t too long, though, and the fact the Ibiza is broader than most small cars means there's less of a fight for shoulder room.
