I am looking to buy a used 3006-07 bmw 550i my quesiton is if this car is going to hold its value into 2012. With the release of more fuel efficient engines, new body styles etc. Or should i lease

also how do you guys like the car... or if there is anything I should get in its place. I am just graduating form college and need a 4 door sedan that fun and classy to drive

Fun car, but SO many people have them. I would wait. BMW will be updating the 5 series soon, causing the current one to lose much of it's value.

Or just lease it; also if your graduating from college, you dont need something as big as a 5..here are some other ideas

audi a4
audi a6
bmw 3 series
mercedes c class

and you might call me crazy, but just look at a vw passat or jetta...both are great to drive (can get passat with a 3.6 V6, jetta with a turbo 4-cyl) and feel like BMWs, just cheaper so you dont pay less...you just miss out on the snob value of the bmw badge
