Choose the mechanism you will enjoy, not the parts count
These CMC models suit a collector willing to learn small fittings. Their interaction is different: the 904 makes the rear cover’s motion part of the spectacle, while the GTO asks the owner to manage fine straps to reach its engine.
| Model | Main reason to include it | Important limit |
|---|---|---|
| Monte Carlo 904 | Compound rear-cover movement and exposed rear assembly | Visible wheel screws and unsupported front hood. |
| Green 250 GTO | Right-hand-drive-specific detail and layered small fittings | Hood straps difficult to refasten in the inspection. |
The 904 review separates decorative rear straps from functional locks. The GTO review preserves the reported strap difficulty and inherited body-shape concern. Neither source is a controlled durability test, and this shortlist does not rank long-term reliability.
