I just purchased an Elantra GT Sport, I love the ES, but needed the cargo space. Still in the break-in period, so I can't wait for that to be over. If anyone meets near Columbus, Ohio feel free to let me know, I would love to join in.
The cargo space is nice and I'll probably be kicking myself in the future for not going for it. In Canada we can't get the manual with the navigation though so it was a tougher sell. The GT is not the prettiest on the exterior, but I like the interior better than the ES and the red shift knob is cool.
I hear you on the break-in period, good luck with getting through that!
