I have owned and still own "luxury" brands although I hate that term as I think items that they are calling luxury are just good practices and build quality. Yes, I can be a bit particular but not a snob. Volvo may not be the most reliable these days but the materials that they use on their interior are very nice and can't really be compared with Kia. Yes, companies like Mazda, Kia, Hyundai etc but some "luxury" touches and materials in place but they still cut some corners with hard plastics below the belt line, plastic knobs that don't quite have that feel etc. They make up for it with better reliability usually but I find that their interiors don't wear as nice and age a lot faster. I was on the Carvana web site the other day looking at some used
Palisade and maybe it was from people not treating them as they would a BMW, but the seats looked like crap, there were scratches all around the rear portion hard plastic on the center console and the lid looked like it was not aligning properly. Part of the headliner looked to be sagging etc. This on a 20k mile car. Maybe that particular car was abused but it reinforced my impression that the interiors of some more budget-friendly vehicles have a nice veneer but not the same attention to material longevity as the "luxury" brands.
My Lexus GX460 has 100k miles on it but the interior looks great. Before that I had a CX-9 Signature that I only kept for one year but I noticed the hard plastics on the lower door panels were getting scuffed and looking ratty among some other things. Before that I had an X5 whose interior still looked great after 5 years with no rattles of much wear to speak of (it did break down all the time once the warranty expired though). In addition, the level of service you get at the dealership plays into people's brand perceptions and choices.
In addition, US shoppers are willing to pay MSRP or less on things. I work in sales and in the Middle East, we mark up our products heavily so that we can discount them 70% as that is what is expected. In the US, we discount 30%. If a customer comes to us and we mark up our product 10%, we would lose that customer.
I guess my point is, Kia should have started with a higher MSRP and maybe some nicer interior touches but I think they saved that for the Genesis. Most Americans will bulk at paying over MSRP but if the Telluride was $60k and discounted to $55, they would buy it. Perceived value is a big deal in the human psyche. Two shampoos on the shelf, one $3 and one $12 could have the exact same ingredients but the $12 will be perceived to be better. Give a customer a $2 off coupon for the $12 shampoo and they will happily pick it and think they got a great deal. Tell them that you are marking up the $3 shampoo to $4 due to market demand and they will also buy the $12 one because F you.
