EVIDENCE-BACKED ESTIMATES, NOT APPRAISALS · PROJECTIONS ASSUME THE CLEAN-SALE TREND HOLDS, NOT A GUARANTEE · MARKET LIQUIDITY READS 11 CLEAN SALES IN THE TRAILING 12 MONTHS AND 47 RECORDED ASKS AT SNAPSHOT, ALL TRIMS, COVERED SOURCES · DATA SNAPSHOT 2026-10-16 · DAILY CHECKS, PARTIAL COVERAGE
THE EVIDENCE ROOM
We've done our due diligence: recorded sales, kept receipts, every number traceable. But markets keep their gray areas, and every rule has its exceptions. Where they appear, we say so plainly.
SOLD EVIDENCE
Reported Shelby GT500 sales with receipts. Each card identifies the reported price basis and title status where known. 28 clean sales match collector · under 10k mi; matching mileage appears first. Other mileages remain as context. The chart shows the full selected-trim history across mileages. Latest recorded sale: 2026-08-29. The current estimate is separate from that historical line.
46 recorded clean Shelby GT500 sales across all mileages. Sale dates are historical; a new data snapshot does not make an old sale current. Hammer prices exclude buyer fees; buyer totals and unstated fees are labeled separately.
ASKING MARKET
Asks are not sales. Recorded Shelby GT500 listings retained from U.S. sources. Each receipt carries its own observation or verification date. 7 classified asks match collector · under 10k mi; other mileages follow. 18 additional listings have an unverified trim and appear separately in the same carousel.
At most 10 representative unique asking vehicles are selected per model year across all sources and trims. The full eligible sample remains available to asking summaries.
Data snapshot 2026-10-16. 15 classified Shelby GT500 asks · 18 with trim unverified. Daily checks cover supported sources, not every US listing. Missing location or original-market evidence is not proof of US delivery. Unknown trim or mileage is never treated as a matching comparable. Missing details remain visible for inspection.
COLORS & PRODUCTION
Ford published no per-color production counts for the 2021 model year. Palette from paint-code references; Fighter Jet Gray was Mach 1 only and Performance Blue was Shelby GT500 only. No color price premium is assumed without supported sale evidence; if the record ever supports one, it is noted on that color's own card.
COMMUNITY HEAT
The pulse from the enthusiast crowd: what people are hunting, praising, and whispering about, digested here once our community crawler comes online. It reads the room; it never moves the number.
no community data collected yet. X/Reddit adapters land behind the compliant boundary in ingestion/community.py; attention counts and themes will appear here, clearly separated from valuation.
THE DEBRIEF
A straight word before you go. The values upstairs come from recorded sales, real cars and real money with receipts kept, fitted into a simple, versioned model. Sales and asking prices are never blended.
Know the edges: a branded title, a heavy build, or a truly exceptional example trades in its own lane, apart from these numbers. And when there is not enough data to price something honestly, we say so. We never invent one.
Estimates, not appraisals. Enjoy the room.

How often does a 2021 Ford Mustang come up for sale?
The 2021 Ford Mustang's market liquidity currently reads Uncommon: 11 recorded clean-title sales in the trailing 12 months across the venues we track, with 47 recorded asks in the 2026-10-16 snapshot, across all trims and mileages. Daily coverage is partial. This describes observed trading frequency in covered sources, not how quickly an individual listing sells.
Do modifications lower a 2021 Ford Mustang's value?
The core 2021 Ford Mustang estimate covers clean title, unmodified or lightly modified, ordinary condition. Heavily modified builds, branded titles, and truly exceptional examples trade in their own lanes, so they are kept out of the core model rather than priced with a guess. A modified car needs its own receipts, not a discount rule.
