You're right, there is something to be said about a RWD V8 sports sedan:
Of what money that people do have to spend, they are more interested in spending in something that is quality, long-lasting and the most for their weak dollar. Splurging on a RWD V8 sport sedan doesn't seem like a smart decision, especially when the G8 is such a watered-down, cheapened-down version of Holden's better vehicles.
Especially in MI, every road is grid pattern. And every road is now congested with traffic, and stop lights every mile. Not alot of times to use all that "power". So why waste the gas? What's the point anymore??
I'm not trying to sound like a total downer, because I share the same passion for RWD V8's. I'm just alot more realistic about our times and our country's financial situation. Therefore, I adjust, rather than suffer.
The cost-to-own a G8 is higher, with less return in the end, especially when that thing turns into a rattle-box like every GM. Holden designed the gem, and GM tainted it. Atleast with the GTO, nothing was changed other than the exterior. The integrity and quality of the interior maintained the same. And they really planned on selling a ton of G8's which makes it even less special. Same thing with the Camaro, they really expect to sell 100,000 of these a year with the way things are and the way gas prices are going. Even if they did, once again, just another flooded market with Camaro's. You don't see 1999-2004 Mustang's holding their value whatsoever.
I know this is all off topic, but to stay relevant - The Mazda 6 is going to shock everyone and will continue to be the more profitable automaker out there. They build cars people want to own, drive, and enjoy. Not just some low quality/high quantity seller like the rest of the automakers. That's where the times have changed. Corporations can't get by on selling cheap garbage in high quantities. They actually have to step up and build something worth the price they're charging. And i'd be thrilled to spend $25k on a Mazda 6, compared to a piece of s*** Pontiac G6/G8 for $25-$28k, a boring to drive Honda Accord, or an over-priced and not-much-better-than-domestic Camry.
Speaking on Toyota, i'm utterly disappointed with them. After actually taking a deeper look at their cars, they honestly arn't much better off than alot of the domestics. Loads of plastic everywhere, and cheap interiors. The only thing that holds up way better than domestics are the powertrain and engines. Otherwise, it's the same garbage on the inside. The place where you spend the most time really.
/end soapbox.
