My brother had a Range Rover supercharged (not sport). He liked it, but didn't love it and he ended up only keeping it for a year. One thing he absolutely hated was the handling and I can't imagine the sport will be that much better. It's worth keeping in mind that they are changing the range rover sport in 2014.
