Quick answer
For most builders, the COBI Sd.Kfz. 138/1 Grille Ausf. M #2665 is the best entry point: it delivers a complete self-propelled gun experience at a lower price and manageable size. If you want a larger, more detailed centerpiece, the Executive Edition Wespe #2598 justifies its higher cost with 855 elements and 1:28 scale. The Hummel #2663 sits between them but is not covered by the product records here, so base your choice on the Grille and Wespe facts plus your preferred scale and budget.
What separates these self-propelled guns
COBI's self-propelled gun lineup spans different chassis, scales, and part counts. The Grille #2665 is a Sturmpanzer 38(t) Grille Ausf. M, a German self-propelled gun on a Panzer 38(t) chassis. The Wespe #2598 is an Executive Edition model of the Sd.Kfz.124 Wespe, built on a Panzer II chassis and armed with a 10.5cm leFH 18 howitzer. The Hummel #2663 is a third option, but the supplied catalog facts for this article cover only the Grille and Wespe, so I will not guess its specifications. What matters for your decision is that the Wespe is explicitly described as 855 elements at 1:28 scale, while the Grille's part count and scale are not listed in the supplied facts. That gap is a real limitation: if exact scale matching matters to you, the Wespe is the only one of the two with a confirmed modeling scale.
Build experience and display footprint
The Wespe Executive Edition is the most demanding build of the two confirmed sets. At 855 elements and 1:28 scale, it is a substantial model that will take several sessions and occupy a meaningful shelf footprint. The Grille #2665 is positioned as a set that develops model-building skills while teaching about armored warfare, which suggests a more approachable build, though COBI does not list its element count in the supplied facts. If you are new to military brick models, starting with the Grille reduces the risk of frustration. If you already build 1:28 COBI vehicles, the Wespe will feel consistent with that scale and reward the extra time.
How to choose without overbuying
Match the set to the space you actually have. A 1:28 Wespe needs more display room than a smaller self-propelled gun, and its 855 elements mean a longer build. The Grille is the safer choice if you want a self-propelled gun on a budget or as a first artillery model. The Hummel #2663 is a valid third option, but since the supplied facts do not include its specifications, treat it as a set to research separately rather than assume it sits between the other two in size or price. Check the catalog page for its element count and scale before committing.
Trade-offs at a glance
- Grille #2665: lower cost, less confirmed detail: The Grille is the more affordable self-propelled gun in this comparison, but COBI does not list its element count or scale in the supplied facts. You get a complete German self-propelled gun model without the Executive Edition premium. Choose the Grille if budget and a manageable build matter more than confirmed 1:28 scale.
- Wespe #2598: higher cost, confirmed 1:28 scale: At 855 elements and 1:28 scale, the Wespe Executive Edition is a larger investment in both money and building time. The Panzer II chassis and 10.5cm howitzer are the defining features. Choose the Wespe if you want a detailed centerpiece and already collect 1:28 COBI models.
- Hummel #2663: unverified in this comparison: The Hummel is a known COBI self-propelled gun, but the supplied product records for this article do not include its specifications. Comparing it directly to the Grille and Wespe would require guessing. Research the Hummel's scale and element count separately before deciding it is the middle option.
