used-car-buying

Eleven source-cited references on actually buying a used car, built from /rabbithole research — SEC filings, regulatory records, official auction-site documentation, and independent industry reporting, with every claim carrying its own citation.

What’s in it

The platforms — Copart and IAAI directly, plus AutoBidMaster for buyers without a dealer license.
The mechanics — how to actually read a listing’s title-status and damage fields, and how to bid and win without overpaying.
The judgment calls — valuing a salvage or rebuilt-title car and estimating repair cost from listing photos alone, before you’ve ever seen the car in person.
Doing it right — individual buyer best practices, the mistakes newbies actually make, how to pick a genuinely best-value car, and cheaper channels than a salvage auction altogether.

A handful of source citations in the underlying research were truncated mid-URL by the compile pipeline; those specific broken links were filtered out rather than published as if valid, and every remaining citation resolves.

  Used-car and salvage-auction buying hub: Copart and IAAI auction mechanics, AutoBidMaster
  and other bidding brokers for buyers without a dealer license, reading a listing's
  title-status/damage/odometer fields, bidding strategy and fees, individual-buyer best
  practices, salvage/clean-title vehicle valuation, repair-cost estimation from listing
  photos, common newbie mistakes, picking a genuinely best-value used car, and low-cost
  alternatives to salvage auctions (dealer wholesale auctions, private-party, CPO, credit-
  union buying programs). TRIGGER: "how do I buy a car at Copart/IAAI", "is AutoBidMaster
  worth it", "what does Run and Drive mean", "how much should I bid on this salvage title",
  "how much will this car cost to repair", "what's a salvage brand going to cost me at
  resale", "best value used car", "cheaper ways to buy a used car than an auction",
  "mistakes to avoid buying a salvage car". SKIP: new-car financing/loans/leasing → belongs
  to a personal-finance skill, not this one; general auto repair/maintenance procedures
  once a car is already owned → a repair-specific reference, not this hub.

# Used Car Buying

Reference hub for buying a used car through salvage/insurance auctions (Copart, IAAI) or
through the cheaper alternatives to them. Compiled from source-cited `/rabbithole` research
(SEC filings, regulatory records, official auction-site documentation, and independent
industry reporting) — every claim in each reference file below carries its own citation.
Start from the routing table, then read the listed `references/…md` file before answering
a deep question.

## Notes on this research

- Every reference file lists its real sources under `## Sources`; no claim was invented.
- A handful of source citations in the underlying compiled packs were truncated mid-URL by
  the research pipeline (a known pipeline issue, not something fixed by rewriting the
  source) — those specific broken citations were filtered out rather than published as if
  valid. The surrounding claim text is unaffected.
- This is a genuinely new domain for this skill tree — there was no prior used-car or
  auto-auction coverage to fold into or conflict with.
