Well I have purchased a 1996 mxz 583. My question is, is it really a 1996? The hood is purple with yellow colored vents, it says mxz 583. During serches for parts and just information, I have yet to see a 1996 mxz 583 that is not entirely yellow. What is the difference between the colors, yellow or the purple. I see a lot of formula z and mach z with the puple color. Thanks for any input.
