The GT350 is listed as being about 1000 of that 1630...the Roush definitely has a cost to insure advantage; you do have to be careful to insure the Roush portion of that as well, as a VIN explosion will just show a Mustang GT, but Allstate (3 independent sources: our agent, corporate, and the agent at the dealer) confirmed that as long as the Roush window sticker is in their system it's fine.
