Also weird flex on that list, as the only difference between the Cadillac and Chevy models are the sticker price. They're badge engineered cars.

That said, from experience, where they put Cadillac is about right for all GM brands. I'd also tend to put Kia above the the VW/Porche group's brands (since everything tends to go wrong while still under warranty, so if it survives the warranty it'll probably survive another decade).
