For me it's been more of "You spent how much on a Kia??" lol
[MENTION=536]StingerGT68[/MENTION], and isn't that how powerful branding can be. And therein is the question's perspective and perception.
There IS a reason companies spent up to $5.5 million for a Super Bowl ad - it works! Kia's was 60 seconds, so somewhere in that $10m+ range. Kia also has high-end malls with small storefronts next to Apple, Victoria Secrets, etc... with just the Stinger. Just a Stinger store front!
Hyundai learned a LOT about brand and how important it is to make a separate luxury division with it's own label. It's already helping Genesis vehicles in a big way, and soon their own dealerships I believe. That's big, really big, because brand makes a huge influence on people.
Kia? Not sure what they are going to do. My best guess is they watch Genesis and see how successful it is in the next two-years. If it blooms, Kia will follow suit, but it will be tricky. Kia/Hyundai are akin to Chevy/Pontiac. One is mainstream, while the other is the sporty version...
Genesis vehicles and their Kia brethren (K900, Cadenza), are not designed for sport, but luxury. And one cannot be a pretender in the luxury market space in what one is. The Stinger flows well into the low-end luxury realm, with a heck of a lot of sport behind it. That's Kia's luxury brand (not the K900 or Cadenza)... Since Kia's high-end are all shared platforms, this is going to be tricky, because any chassis beyond the G70 (Stinger and G70 Genesis) are not designed for the performance direction...
Would Hyundai/Kia ever sign off on more Kia only high-end performance/luxury vehicles? Not likely. Not enough volume to justify and keep pricing down.
Sorry to digress, but it begs the question of what Kia does? The other cost saving move, is just kill off the K900 and Cadenza and leave the Stinger as the flagship vehicle of the brand. Probably the best move overall. It'll increase Stinger sales a bit, an solidify Kia as sport.
