Yes. Elantra is a diwngrade from Sonata and you can get into a mid- loaded model.
You have to wait till your lease is up or else you'll have to pay the balance or they'll tack it on to your new lease and the payments would probably be the same.
I traded my car which was not a lease. Bought a 2015 Hyundai Elantra Sport. Payments were lower than that.
