I know I may be biased because I actually own the car, but why do people keep complaining about the materials in the Cadillac? The same hard plastics in the Supra can be found in the Corolla. Having been in both cars I agree the Supra is tight, even more so than the C8 but the materials are very Camry if you ask me. All the shift stalks are the same. The materials in the M3 are shared with the 330i, again all the hardware being the same. They keep saying it feels very Chevy but go actually sit in a Malibu or even a Camaro and you immediately realize that while the design language is similar it definitely is NOT the same switch gear, nor materials. GM does have their injection molded formula that they use across all their cars just like everyone else but the Caddy even the base CT4 is miles ahead of the rest of GM's interiors until you get to something like the GMC Denali.
I personally don't think the 4 looks bad at all from the rear, but I've always been a function-dictates form kind of guy.
