It's really interesting to hear these comments. I agree with many of you guys. I'm definitely excited to at the possibility of the return of this car; it does raise very interesting questions though. Though the article only mentions the G8 (Zeta), the pics I've see on the net, and here, are of the middle eastern Caprice (LWB Zeta). I hope that it's the LWB Zeta that makes it to the NA market. Also, would the Chevy version be the Caprice, with the Imala becoming the high performance trim (as it has been before), or will GM keep the Impala model name for it's Chevy flagship and then offer the SS trim for it's high performance model?
Also, I agree that this car just SCREAMS next gen Park Ave, replacing the Lucerne. It could if done right, it could easily be marketing as a full size value alternative to the LS460L for thousands less... Along with the LAX and either the Regal coming here as a "sports sedan" or the next gen Astra as a "entry model," you have a full sedan lineup for the brand. I don't think a full size Park Ave (or Roadmaster, or Invicta) would compete with the Chevy version or with Caddy Full Sizer... It should be very luxurious with a nice dose of tech features and a semi-athletic ride. Lots of lux with the credentials on paper to justify a mid $50k-ish price that would still be tens of thousands less than the Germans, the LS460L, new Jag XJL, AND A CADDY FLAGHSHIP. I also have faith that Fritz and Bob would spend the money to truly differentiate these models from one another... it's worth the investment. It's not a secret that although a car shares a basic platform, it can still have different over all lengths, designs, driving characteristics and even widths and wheelbases... If that were to happen, it certainly would not be a mere rebadge, but just a shared platform. Toyota's Camry platform is proof positive this approach can work.
If all the above were to happen, then the question of Caddy's RWD flagship comes into questions. Cadillac really needs a lineup that mirrors the conventional lux competition. It's already reported that CTS will grow to full 5-Series competition, and a true 3-Series competitor is also coming (as well as an ES competitor). IMHO, GM should leave the ES beater to the new LAX, but hey, that's just me. If I had to choose between a Caddy LWB Zeta and a Buick LWB Zeta, I'd pick the Caddy in a heartbeat. However, I think that there is room for three LWB Zetas as long as they're different cars... Caddy/Holden needs it to be a no excuses Flagship that has all of the tech, tricks, and driving dynamics of the 7-Series, IMO. I also think that a Caddy flagship should have a stand and LWB version of the car, this would also put it on even footing with the German (etc.) competition. The problem is where would the money come from for all of this... I don't know... I haven't seen the books and I don't work for GM. I just know that GM can't come half-ass anymore because the customer won't put up with it.
From a business standpoint, I would argue that having Chevy, Buick, and Caddy have a version of a flexible, next gen LWB Zeta would help pay development costs down the road. I guess we'll see what happens.
