What is Junk Mechanics?
Junk Mechanics Wiki is a source-first fan guide for the Roblox car-flipping experience by Oil Leak. Verified Roblox API metadata, peer-confirmed gamepass prices, and a brand-by-brand code tracker separate confirmed data from community research.
Category data powers item cards, search records, tier pages, and internal links, so updates stay consistent.
Codes, news, guides, rankings, tools, and wiki entries can be enabled only when they fit the target Roblox game.
Each major topic has a real URL instead of being hidden behind a single homepage anchor.
The interface uses a dark command-center layout, scannable cards, and readable article pages without Fandom-style clutter.
