Well, as I have never had the opportunity to really discuss the Mormon ‘selling-points’, I will only indicate what they teach about salvation:
Mormons believe that their church is “the only true and living church upon the face of the whole earth” (D&C 1:30), the only organization authorized by the Almighty to preach his gospel and administer the ordinances of salvation, the only Church which has power to save" (Mormon Doctrine; 1977 ed, p. 136).
Mormons either deny of pervert every essential doctrine of historic Christianity, including the uniqueness of God, the virgin birth, the Trinity, the authority of Scripture (by relegating it to a position below their other sacred writings), and salvation by grace through faith.

“the plan of salvation is the fullness of the gospel. It includes the Creation, the Fall, the Atonement of Jesus Christ, and all the laws, ordinances, and doctrines of the gospel.”1 Free agency, or the ability to choose for ourselves, is also an integral part of God’s plan. Because of the plan of salvation, all may become perfect through the Atonement of Jesus Christ and live with Heavenly Father again. This plan of salvation is also referred to as the ‘plan of happiness’, ‘plan of redemption’ or the ‘plan of mercy.’ Source
Please see this as it is too lengthy to post here but contains some very clear information.
Some very interesting stuff indeed.
