Trim
An equipment level of a car variant, with its own price, features, and sometimes its own performance figures. The base trim carries the headline price.
Walk into any configurator and the first fork in the road is trim: the ladder of equipment levels a car is sold in, from a plainly equipped base to a fully equipped flagship. Each trim is a distinct product with its own price, and more than upholstery can separate the rungs: wheel sizes can change efficiency, a bigger battery or motor may be tied to upper trims, and so may the drivetrain (FWD versus AWD).
CarPairly's headline price for every car is the base trim's current price in each market, dated and sourced. That gives comparisons one consistent rule, although what counts as base equipment differs by manufacturer.
In CarPairly's catalog the hierarchy runs brand, model, variant, trim — trims belong to a variant, and specs attach at trim level. When two cars seem close, compare like trims: a mid-trim of one against the base of another can invert a price verdict.
