Does anyone know why Revell finds it necessary to have two different boxes for the 2006 Mustang kit. The kit I bought in December shows a photo of the real car with a sticker in the corner which reads "Hot from the Revell garage." The kit I bought today is labeled Revell Muscle with an artist rendition on the box. Instruction sheets for both kits have the same error in step 2 as was pointed out in the Fine Scale Modeler review. Seems to me the money for the new art work would have been better spent correcting the instruction sheet.
