E 92 M3 as your weekend/track toy, and an F10 of some sort as a DD.
That's what I would do, if plenty of money.
if money is a limiting factor, I would stick to the E92 M3 as a DD and track toy. A proportion of the money that you save not getting the E46 and the F10 could be used for the extra fuel consumption on the E92 M3, and you still have left with an excess.
