Per previous comments, get quotes from BMW, Carmax etc... if you can.. also all data you can get from KBB, NADA, Black Book if you can get access etc.. should help if you had it all holistically to see/share.
Here are some values i just pulled... as you can see .. the X5M looks to have effectively bottomed out. The 2103 looks like it's just hitting that flatter part or is very very close to.
