The "R" rear emblem is commonly associated with Volkswagen's performance line, specifically the Volkswagen Golf R and the Volkswagen Arteon R. These models are designed to offer enhanced performance and sporty features compared to their standard counterparts. Additionally, the "R" designation signifies a focus on driving dynamics and performance tuning.
If I recall, that year, the SS emblem on the rear of that car, comes via a black rubber insert, on the pass side of the car, which bolts to the bumper.
Nissan uses a red R on their sport models.
I believe it is the Riviera.
It is probably the Rolls-Royce emblem. It has two R's overlapping that looks like a line is going through it. The other possible brand it may be, is the Buick Riviera.
That would be Dodge, and the emblem is a Ram (goat).
It could be an old Buick emblem.
