The Polo Sedan might seems like a Polo Hatchback with a boot strapped on, but it turns out that Polo Sedan has an extended wheelbase of 82mm from the Polo Hatchback to 2552mm. So you can expect a larger cabin space compared to the Polo Hatchback. As a comparison, Toyota Vios and Honda City has an almost similar 2550mm wheelbase. Besides that, the Polo Sedan looks good and doesn't have the usual awkward rear end eventhough it is based on its hatchback sibling.
The Polo Sedan comes with interior chrome package, which lighten up the rather gloomy cabin. Leather can be found on the steering wheel, gear lever and handbrake lever. All these gives the Polo Sedan a more premium feel.
