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 Skoda Fabia, for example. The only cars in the class that offer more are the Volkswagen Polo and the MPV-shaped Honda Jazz. The Ibiza also has plenty of head room to cater for six-footers.
As with all 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 that the Ibiza is broader than most small cars means there's less of a fight for shoulder room.
