Austin-Healey 3000 VIN Decoder
Austin-Healey 3000 chassis numbers encode body family through BN7, BT7, BJ7 and BJ8. PetrolJunky goes a step further by using serial boundaries to distinguish BN7 and BT7 Mk I cars from their Mk II successors.

Decoder reference
What this decoder page is designed to answer.
The Austin-Healey 3000 needs both prefix and serial
BN7 identifies the two-seat 3000 while BT7 identifies the 2+2, but both prefixes span Mk I and Mk II production. PetrolJunky therefore uses reviewed serial boundaries to separate those generations instead of assigning the model from the prefix alone. BJ7 identifies the later roll-up-window Mk II convertible family and BJ8 the Mk III.
Common plate formatting is accepted
Numbers may appear with an initial H, steering-market letters, slashes or dashes. The universal input normalizes those characters before lookup, allowing forms such as H-BJ8-L/31327 to reach the same registry record as its compact normalized equivalent.
Registry accuracy comes before false precision
The decoder reports seating configuration and supported generation where the chassis system proves them. Exact build dates, paint, trim and originality remain separate provenance facts that can be added later rather than inferred from a chassis number.
