She's a goner, all right.
My guess is either (a) Warmoth's license to build that body style ran out and the cost to renew was too high, or (b) they didn't have a license and someone threatened to sue, or (c) they didn't have a license and their attorneys advised them to knock it off in order to avoid attracting a suit.
Rank speculation, but since I'm a former trial lawyer, they're educated guesses about how such things play out.
Yours truly,
Bagman (Esq.)
