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
Real hammers only. Every card is a completed clean-title Shelby GT500 sale with its receipt. Swipe through the record.
Showing the 15 most recent of 46 recorded clean Shelby GT500 sales. Every recorded sale remains available to the evidence rules; this selected set feeds the matching chart.
ASKING MARKET
Asks are not sales. Live Shelby GT500 asking prices from the nationwide retail market.
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.

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 109 live asks nationwide. Market liquidity is how often clean examples actually trade, not how many were made. Common means fresh comps, tighter prices, quick sales; Ultra Rare means stale comps, wider swings, and when the right one appears there may not be a next one. General read across all trims; individual trims, preservation-mileage cars, and modified builds trade in their own lanes. Uncommon: at least 6 recorded clean sale(s) in the trailing 12 months (thresholds liquidity-v1-2026-08-12).
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.
