I fully support adding Class levels to Dragons and other such big guys. However, I do agree with Someone (sorry) comment that a class level does not equal +1 CR when given to a dragon. As for my personal experience I mostly a handful of sorceror lvls (to give them a certain spell) or customize the dragon itself in someway. For example, I had a dragon who casted as an X lvl bard and had the bardic music abilities, but I didn't actually give the beasty any Bard levels.
In a campaign I play in the final goal of the campiagn is to kill the member of the dragon council that have been corrupted. All members of the dragon council are Half Fiend/ Half Celestial Great Wyrms with 10 or more class levels. Needless to say our 12th lvl party hasn't fought them yet
