It refers to the modification of Japanese luxury automobiles to make them lower and wider in stance, with more aggressive wheels, suspension, and body kits.
As a trend, it differentiates itself from the traditional origins of the term VIP otherwise associated with the concept of a "very important person".
By using JDM cars with modifications associated with limousines, it is said that gangsters could avoid detection by the police and rival gangs.
Common exterior modifications on VIP style cars include modified suspension to achieve a lowered ride height, typically using coilovers or air suspension, and often also modified or custom control arms, suspension knuckles, tie rods and more; 3 piece wheels, often in wide configurations with low offsets that sit flush with the fenders or tuck inside of them; modified exhausts; LED lighting; upgraded larger brakes; and body kits, which can range from simple lip kits or fender flares to more extensive custom widebody setups.
Common interior modifications on VIP style cars include custom upholstery (most commonly leather), window curtains, headrest pillows, seat cushions, tray tables, upgraded stereo systems, illuminated trunk audio displays, storage for champagne flutes and alcoholic drinks, chandeliers, starlight headliners, and more.
