There are some differences, such as the Elite has triple wall wheels (Sport has double), Elite has carbon wrapped seatpost (Sport has alloy or aluminum), Elite has the Zerts in the front carbon fork (Sport does not). The other noticable difference is that the Elite has full Tiagra derailleurs and shifters, whereas the Sport has Sora up front and Tiagra in the rear (I think). So, If you are going to ride this bike lots of miles, the upgrade to the Elite is probably worth it. If you have just a casual interest in road biking the Sport will be fine. I have the Sport and it does everything I want it to do. Not fancy, but it is my first road bike. Maybe I'll get something better in the future, but for now it is great....and I love the white/berry color....YMMV.
