Are they making a new RS4? I've come to realization that for the time present, there is nothing out there worth changing to. I think I will do a reevaluation in the spring and see whats coming. A new M3? Whats that going to run $70-80K? Not won over by anything Audi or BMW has in the mid price lux sedan. I came away liking the 550i even more. Found a review that may express what I mean:

My advice if your in the same market, buy a 550i. If my car's value is now in the mid 20's, its one of the best deals out there for shear driving pleasure
