The 2021 Nissan Altima showcased a strong family identity with its bold V-Motion grille, available in chrome or dark chrome, adorned with the Nissan logo. Its overall shape was sleek and aerodynamic, featuring a sloping "coupe-like" roofline. The body design leaned towards folds rather than curves, giving it a taut appearance, though the extended overhangs and short dash-to-axle distance lent it a slightly old-fashioned look. Modern touches like LED lighting and alloy wheels kept it contemporary. The Altima boasted exceptional fit and finish, with deep lustrous paint and rich chrome details, available in six exterior colours with creative names. Inside, the dashboard was uncluttered, with an 8-inch touchscreen display positioned for safety and convenience. The base model felt basic, but higher trims offered improved materials and stitching, enhancing the overall feel.
The 2022 Mercedes-Benz S-Class retained its fantastic look from the previous year's complete makeover. Despite the trend towards SUVs, the S-Class stood as a testament to the enduring appeal of sedans. With roots tracing back to the 1954 "Ponton" models, the seventh-generation S-Class, code-named "W223," continued as Mercedes-Benz's flagship sedan. Its sleek exterior featured a long distance between the front axle and dashboard, exuding elegance. The proud Mercedes-Benz grille and star hood ornament highlighted its lineage. Inside, the dashboard delighted with open-pore wood trim and a 12.8-inch touchscreen, complemented by a separate 12.3-inch digital instrument panel. The cabin was dressed in high-quality materials, meticulously fitted and assembled, offering a luxurious experience.
