Based on my short interactions with the car.
Compared to other ckd sedans available in our market. It definitely has a very good balanced suspension, offering good comfort and maneuverability. The long wheel base also helps.
But since the front seats can move back A LOT to create huge space for the front passengers, the rear seat isn't anything special. In fact, I might rate a grande better in terms of being chauffeured around, due to the seat posture, height and leg space.
Sportage has much softer suspension compared to a sonata, hence more comfortable in the city. But the rear leg room again is just average.
