LS Models has released the Dasha in several batches. Collectors use the term "LS Models Dasha" broadly, but there are distinct variants:
| Variant | Catalog Number | Livery | Rarity | | :--- | :--- | :--- | :--- | | X 4300 (Original) | LS-43101 | Bleu Moyen / Gris | High (Discontinued) | | TER (Transport Express Régional) | LS-43115 | Multicolored Regionale | Medium | | Infra (Maintenance) | LS-43122 | Yellow & Grey | Extremely Rare | | Corail Téoz | LS-43130 | Silver & Blue | Low (Current) |
Note: The "Infra" yellow version is the holy grail for collectors, often fetching 300-400 Euros on the secondary market.
