Congrats on the ride Brian The E46 is only second to the "mid-year" Corvettes for all time favorites and yes, ahead of the EVO too! BTW there's a guy around the block from me that's got an E46 convertable and his plate reads MMMMMM3!
well, i have a plate recommendatino but i don't know if you'll like it:
XCLUSIV
i actually saw it on a brand new 07 S600. Pearl white with black 22" rims, black with the polished lip...glass roof, the works. Dunno if the m3 fits the bill, but yeah the benz was definitely exclusive.
