You misunderstood what I said. Years ago Chryslers could be compared with Cadillac. However it hasn't been that way for decades. Although, the 300M was a better performance car than what Cadillac had to offer at the time.
First, the crosshair grill has been around for decades. Before the Ram even existed.
Second, it's not stealing. Unless I guess Pontiac stole the split grill from one of it's models (or BMW? I can give misinformation too)
Next up. Dodge had several performance models with it's EEK cars like the Shadow CSX, Spirit R/T and such. The minivans changed the shape of the industry for people movers. The First gen Neons were touted as being worthy of competing with the Civics and such (before later reliability problems). The original cloud cars were renowned for their right size, good handling, frugality and styling. The LH cars introduced Cab Forward design and capable handling in a large car. The LX cars brought RWD back for the masses in the US. The Ram broke the mold for truck styling, and the new one broke the mold again for suspension and handling. The Dakota was the first, and for a long time, the only midsize truck and the only one to for a V8. And of course there's the Viper.
As far as design language goes, clearly you didn't think your post (at all) though. Since the mid 90's Dodge has had very clear styling languages. The 90's - early `00's were the swoopy, cab forward era. The Charger ushered in the more upright and sharp lines design languages. You can see the cues in the headlight detailing, fender flairs, strong lines, and of course the grill among other things.
Not just a split grill, some plastic cladding, and fake hood scoops.
Oh and of course there's the SRT vehicles, which unlike the SS badge, haven't been diluted.
Oh, and the Challenger doesn't have a crosshair grill because the original didn't.
I could go on and on but it's not like you'll pay attention to it.
Oh, so people you know are representative of an entire country?
