Decoder reference
What this decoder page is designed to answer.
Factory-backed Jaguar chassis decoding
PetrolJunky uses reviewed Jaguar Heritage chassis ranges for XK120, XK140, XK150, E-Type Series 1 through Series 3, Mark I, Mark II and early XJ Series 1 cars. Original slash formatting and common suffixes are normalized automatically.
Numeric Jaguar chassis numbers require care
Some six-digit Jaguar numbers overlap the serial space used by BMW, Porsche and Volkswagen. PetrolJunky checks those systems together and refuses to guess when a bare number is genuinely ambiguous.
