Capability changes by version. AutoUnite leaves the number open when the exact evidence is not confirmed.
Use the Guide to understand what changes inside the vehicle instead of reading a specification dump.
Package detail appears only when AutoUnite has enough confirmed information to explain it cleanly.

Live inventory and asking prices are a separate market layer, not permanent vehicle facts.
