The Kia Opirus is an executive car/full-size sedan, manufactured by Kia Motors and marketed over a single generation for model years 2003–2012 globally and 2004-2009 in North America. Having debuted internationally at the 2003 Geneva Motor Show, the four-door, five-passenger, front-engine, front-drive sedan was launched to the North American market at the New York International Auto Show and in San Diego, bearing the Amanti nameplate — and prioritizing luxury content and comfort over dynamic performance and agility.

The Mazda Sentia is a mid-size rear wheel drive luxury car that was sold by Mazda in Japan from 1991 to 1999 over two generations. It replaced the Mazda Luce nameplate on the Mazda H platform, and continued the tradition of being Mazda's largest flagship sedan, which had been in production since the late 1960s.
