Should I do it??

I love my old Mopars and actually drive them all the time BUT I've been wanting a late model Charger or Challenger for awhile now. If I could get a decent trade for some of my old iron I'd be in a late model in a minute. So what if it depreciates? I'll bet that if you get tired of it in a few years you could trade someone back for another old Mopar.
