Ok, first of all Saturn no longer has dent resistant door panels. 2nd the Buick Epsilon should compete with the ES, that is not Saturn's territory. The current 9-3 starts at close to $30k, again not Saturn's territory except for the upper end, plus Saab is a niche brand and the 9-3 is going to be the size of a Cruze, and the 9-5 starts at $38k. No Saturn sedan should cost that much, ever. If the Insignia/Aura is priced at Passat levels ($24k to $33k or so, forget the VR6), it should not overlap too much with the Buick Epsilon, which should start at $31k if comparably equipped to a base ES ($34k). Aura and Malibu should have different enough styling that they attract different customers. Malibu should also be priced as low as $21k for a base model. Even if they attract some of the same customers, the midsize car market is so big, does it really matter? It will likely get even bigger as people move away from SUVs and large sedans but don't want to move all the way down to a compact vehicle.
There is no Pontiac Epsilon AFAIK.
I was thinking about this, and there's no evidence that the vehicle is getting dumbed down. That may be the case in the end, but I am actually wondering if it's just going to be an MCE of the Insignia, or something of the effect, especially on the interior. Insignia will be dated by the time the NG Aura arrives, anyways.
