All they do is give you a tall car. Look at roof height for Kia Soul at 63.4" compared to VW Golf or Hyunsai Elantr GT at 58". 5" is more than a tippy toe stretch.
The Soul gets 29mpg and the Hyundai GT gets 37.
The Hyundai GT looks like it'll be a more comfortable vehicle and less likely to get tossed in high winds with a load on the roof.
