Ferrari 312PDoor lines can separate similar cars
Ferrari 312P rewards a closer look along the sides. On some Hong Kong bodies the feature lines are raised; on others they are recessed or incomplete. That is a more useful comparison than calling every red or yellow car the same version.

A Grand Prix casting with an opening rear hatch
Ferrari 312P joined Hot Wheels for 1970. The rear hatch opens over the engine. US examples have clear glazing; Hong Kong examples have blue glazing. Black interiors are recorded for both. An unusual interior-color claim needs a documented comparison and a check for exchanged parts.
Check the hatch in its closed position before asking for an open view. Uneven fit, damaged edges or a loose hinge are condition issues worth recording without forcing the mechanism.
Raised and recessed lines
The Hong Kong bodies include complete recessed feature lines, incomplete recessed lines and raised lines. Ask for sharp side photographs with light falling across the surface; a flat, brightly lit image can conceal shallow detail.
Rear trim also differs. The guide describes the US black-painted panel extending to the hatch edge, while the Hong Kong version leaves a line of body color visible.
Stickers tell only part of the history
Some cars came with a separate number-and-logo sticker sheet; others had factory-applied markings. Missing or crooked stickers therefore need context, and replacement decals should be disclosed.
Separate paint condition from sticker condition in your notes. A clean sticker over a chipped panel does not make the surrounding finish untouched. The yellow example pictured here should be compared by its own visible details, not by a value assigned to every car of that color.
