ACME Pontiac Models: Tempest Super Duty vs Firebird Ram Air II

Choose the 1963 Tempest Super Duty for the Wynn Engineering Co. subject, or the 1968 Firebird for the First Ram Air II and Weidner Pontiac identification. These white ACME 1:18 models represent different Pontiacs, not two trims of the same body.
Tempest Super Duty: A1805903
The 1963 Wynn Engineering Tempest is described in white with a blue interior. It is the focused choice for a Tempest collection or someone specifically interested in this named Super Duty subject.
The interior color is a useful detail for a model that will be viewed through open doors. Its description lists an opening hood, doors and trunk, steerable wheels and wired and plumbed engine detail.
Wynn Engineering Co. identifies the advertised miniature's theme. It does not establish that the package contains company memorabilia, a signed insert or a particular vehicle's history.
Firebird First Ram Air II: A1805221
The 1968 Weidner Pontiac Firebird is offered in white with red stripes. Its First Ram Air II wording belongs to the release identification and distinguishes it from a generic white Firebird.
Like the Tempest, it lists opening hood, doors and trunk, steerable wheels and wired and plumbed engine detail. A detailed chassis is also identified. Choose it when the Firebird body and the specifically named Ram Air II subject are what you want to add.
This comparison does not turn the First wording into an independently verified claim about production chronology. Nor does it assign a full-size horsepower figure or race result that the buying decision does not require.
Which fills the gap in your Pontiac shelf?
A collection already dominated by Firebirds may benefit from the different 1963 Tempest subject. A Firebird-specific collection should stay with the correct Firebird release rather than choose the Tempest simply because both are white Pontiacs with opening hoods.
A pair can show two named subjects separated by five represented model years. These are individual complete-car purchases, not a boxed Pontiac two-pack. Any shared display base or matching case arrangement must be planned separately.
Compare the footprint and edition wording
The Tempest is listed at approximately 10 by 4 by 3 inches, while the Firebird is approximately 10.5 by 4 by 3 inches. Both use diecast construction with plastic components and rubber tires. Allow room beyond those closed-model figures for open panels.
The respective advertised edition quantities are 315 and 306 pieces. Such a small numerical difference is not a useful reason to override your vehicle preference. These are release figures, not current stock counts or evidence of resale demand.
Match the year, body and exact A1805903 or A1805221 code, then review current availability in the Acme Models & Collectibles collection.
