Its so nice to see fellow financially responsible boarders here.

I've got one financially irresponsible suggestion.

Try a NBT evo retrofit.
-You now have modern electronics in a wonderfully capable car for 1/8th cost (assuming a new one is $80k).

I will say that the x5 4.8 is me favorite daily car over the e46 M3 and e60 M5.

Eventually in my old age I will prefer convenience over road feel and move to a newer drive by wire ( no steering column) bimmer.

But not yet.

My vote obviously is to keep it.
