I had a 2013 Limited and a year later I upgraded to the Sport. I loved my limited when I had it and I got so many compliments on it. To me there are some things on the limited I had as options that just made me feel safer with my family in the vehicle while on cross country road trips. The automatic wipers, the collision warning and lane keep assist were all so amazing when we would suddenly hit some nasty weather.
Now I traded in for the 2014 Sport, and I love the acceleration and especially the look, but when I want to have some real fun I leave my kids at home. I think I ended up losing about 7k in value on the limited with the trade in, which considering I had put 26k miles on it in one year was worth it to me.
As others have mentioned, I loved my limited and everything about it, never had a single issue other than the a-pillar blowing clean off on the interstate lol. Oh I also miss the heated steering wheel feature, I actually used that every day during the winter months here because I would have to pass through a security gate to get on base and trying to fumble for an I.D. with gloves on is no fun.
Just decide if that extra power and that different look are that much more important to you, to now go about dropping even more coin (it was to me). Regardless how you do it though you will certainly lose money, but only you can decide if its really worth it.
Also I was going to say around here, the limiteds in certain trims and features have been kinda slim lately. Ive known of the dealerships around here to offer more on a trade in for a vehicle type they have had people coming in looking for but didn't have on hand (they know it will sell fast). The dealer is just going to make more money off of your vehicle anyway, so don't be afraid to get a quote from other dealerships as well on trade in value and on the sport price, you may just get lucky
