I believe that the ZX they are referring to is actually an MXZ-X which of course books higher. It is still the REV chassis. If yours is a non X sled than it is listed as the MXZ 600HO Sport. The adrenaline and trail sleds listed are the old chassis.On NADA- a 03 REV 600 HO with reverse, is it a 600 HO (sport or adreniline), or a 600 HO ZX RER. The ZX RER sled books higher, but I thought the ZX was the traditional style sled, not a REV.
Thanks in advance.
Hope this helps.
