All makes
4 researched, 30 listed and queued. Coverage is deliberately narrow and deep — one chassis family documented properly beats a thin row for every car ever built, so a make appears in full only once there is real research behind it.

Index — every make
Greyed makes are listed but not researched — no specification, no issue records, no prices. They are here so the index is honest about what is missing rather than quietly omitting it.
Engines indexed
Engine codes are first-class objects — searchable, linkable, and carrying their own issue lists across every car they were fitted to.
Chassis indexed
Next in the queue: Audi B7/B8, Mercedes W204/W211, VW Mk5/Mk6, and the 2000s Toyota and Lexus sixes — chosen for cross-shopping rather than popularity, because comparison only becomes useful once both sides exist. See coverage.
