About the vehicles in this guide
This guide includes cars, SUVs, people movers and utes with a recorded production period overlapping 1990 onward. Commercial vans and trucks are outside this selection. A vehicle built before 1990 can appear if its production continued into that period.
The available catalogue includes vehicle versions first recorded up to Feb 2022. Newer models may be missing. “From” means the catalogue has no end date; it does not confirm that a vehicle is still in production. Catalogue dates are not Australian registration or sale dates. Confirm your actual vehicle before using specifications or ordering parts.
Your VIN, build month and body style help distinguish cars with the same badge.
