About this car

What a Brand Is

brand is the manufacturer, spelled as that manufacturer writes. model is what the manufacturer calls that vehicle. Never put both in one field, and never put one in the other’s field.

Spell it the way the manufacturer does. Initialisms stay upper-case — BMW, BYD, GMC, MG, KGM, DS, SEAT — and names that are ordinary words keep their own form: McLaren, Mini, Rolls-Royce, Land Rover. Do not Title-Case an initialism (Bmw is wrong) and do not upper-case a word (Singer is wrong). Write the name in Latin script even when the listing does not: 현대 is Hyundai, 시보레 is Chevrolet, 기아 is Kia.

Never emit a fragment. Aud, Toy, Hyund_Ahd and Je are all real outputs from a truncated source field. If the text holds only part of a name and you recognise the manufacturer, write the full name; if you do not recognise it, answer null. Never copy an underscore, a bracket, a colon or a piece of this instruction into brand — :Lower, __Typew and .Na are not names.
