I like the Magnum too for the reasons already stated. Plus, I like the chiseled, muscular look of the Magnum as oppose to the rolling jelly bean look of the GTO.
To be fair, the GTO isn't so bad but I wouldn't really consider getting one over a Magnum and if Dodge plays their cards right, the Charger will split the difference and make the best of both worlds. From my understanding the Charger will be intro'd later this year and be in production by late 2005 and the sketches I recently saw were awesome. If they produce what the drawing indicated, it will be the next big thing after the 05 Mustang and might make for a great rivalry.
But I wouldnt mind having the Magnum if it had the Hemi inside. Good amount of power and enough room to haul stuff to college. And when you race a dumb ricer on the street, you can tell them "You just got beat by a station wagon! HAHAHHAHAHHAHAHA"
