So i'm trying to wrap my head around OEM/Aftermarket Refs/Cars relationship but things seems messy or missing data or i'm just dumb to get it.
let's say a part listed with OEM XXX
if you track the part you'll get let's say 2 variants/parts each has a slightly different list of compatible vehicules
PART n°1 / has 2 OEM's XXX1 and XXX2 / compatible with cars C1 and C2
PART n°2 / has 2 OEM's XXX2 and XXX3 / compatible with cars C1 and C4
since OEM XXX2 is shared between the two, isin't safe to say that PART n°2 is compatible with cars C1,C2 and C4 same is true for PART n°1 it becomes compatible with all C1,C2 and C4 Or is there something preventing cross reference the presence shared OEM ?
