Model years and trims, handled like a grid.

A powersports listing is a point in a grid rather than a one-off object. The same machine exists across three model years and four trims, and a buyer comparing them needs the grid, not a wall of near-identical listings.

Two units differing only in color are two things a buyer chooses between. Colorway needs to be a field on the record so it can be shown, filtered and photographed, not a word at the end of a title.

A new unit is a configuration, quoted with freight and setup. A used unit is a specific machine with hours and a history. Forcing both through one listing shape is what makes most dealer catalogs awkward.

Engine, engine hours, length, beam, and whether the trailer is included. A marine listing that omits them sends every buyer to the phone to ask the same four questions.

Several powersports and marine manufacturers publish model data. Where yours does, new units can come in from it. Which brands you carry decides whether that is on the table, so it gets checked before it is quoted.

Type, brand, year, price and, for used, hours. A buyer arrives knowing roughly what they want and needs to get to the three units that match in a couple of taps.
