This is the same Larry Wood-designed Cadillac Seville casting based on the first-generation model with the "bustle-back" trunk.
The model number 4356 corresponds to the 1983 release of the Cadillac Seville in the premium "Real Riders" series.
This version is distinguished from its mainline counterpart by its wheels and paint scheme. It was released in metalflake gray with detailed red and black side stripes. The defining feature is the rubber Real Riders tires, which are smooth blackwalls mounted on chrome 5-spoke (5SP) wheels, giving it a more luxurious and realistic look.
This is a premium version of the mainline Cadillac Seville casting (1698-a), with the primary difference being the wheels and paint finish.
The 1983 Real Riders release is the primary special edition of this casting from that era. Mainline versions with plastic wheels were produced in different colors.
