 ## Features
 
-- **633 cars, 24 brands, 1940s → 2020s.** Ferrari, Lamborghini, McLaren, Pagani, Koenigsegg, Bugatti, Porsche, Rolls-Royce, Aston Martin, Lotus, Rimac, Hennessey, plus Japanese and American icons.

 - **Every image is free-license.** CC0, CC BY, CC BY-SA, GFDL, Public Domain, or Free Art. Every image ships with a JSON attribution file. See [`CREDITS.md`](CREDITS.md).
 - **Smart lookup.** Type `--car chiron` or `--car "rolls royce ghost"` or `--car "porsche 911"` — it resolves aliases, matches by tokens, corrects typos, and shows a numbered picker when multiple cars fit.
 - **Real images or ANSI fallback**, chosen automatically based on your terminal's capabilities. Force one mode with `--set-mode auto|ansi`.
 - **Pokemon mixing is opt-in.** The installer asks; you can toggle later with `--set-mix on|off`.
-- **Vintage cars are opt-in.** Default install is modern (2000+). Add pre-2000 cars any time with `./install-vintage.sh`.
+- **Vintage cars are opt-in.** Default install is modern (2000+). Add pre-2000 cars any time with `--install-vintage` or `./install-vintage.sh`.
 - **`--doctor`** health check tells you exactly what's wrong when something isn't working.
 - **Contributor scripts** for adding new cars (`add_car.py`) or replacing existing images (`manual_override.py`) with automated background removal and license validation.
 - **Zero background daemons, zero telemetry, zero non-standard paths.** Uses XDG directories.

 ## Vintage cars
 
-Vintage = pre-2000. Off by default because most people want modern cars.
+Vintage = pre-2000. Off by default because most people want modern cars,
+but easy to add or remove anytime — either from the binary or from the
+cloned source repo.
 
-**Add vintage cars** to an existing install:
+### From the installed binary
+
+**Add vintage cars:**
 
 ```bash
-cd path/to/hypercar-colorscripts/cli
-./install-vintage.sh
+hypercar-colorscripts --install-vintage
 ```
 
-Shows disk impact (~15 MB), asks confirmation, adds the cars. Idempotent — safe to re-run.
+The binary looks for your source clone at these locations, in order:
+
+1. `$HYPERCAR_SRC` (if set)
+2. Current directory
+3. `~/hypercar-colorscripts`, `~/car-test/hypercar-colorscripts`,
+   `~/projects/hypercar-colorscripts`, `~/src/hypercar-colorscripts`,
+   `~/Documents/hypercar-colorscripts`, `~/Downloads/hypercar-colorscripts`
 
-**Remove vintage cars** from an existing install:
+If found, it runs `install-vintage.sh` automatically. If not found, it
+prints clone instructions with the `HYPERCAR_SRC` escape hatch.
+
+**Remove vintage cars:**
 
 ```bash
-./uninstall-vintage.sh
+hypercar-colorscripts --uninstall-vintage
 ```
 
-Works even without the cloned repo — operates entirely on `~/.local/share/hypercar-colorscripts/`. To bring vintage back later, re-run `./install-vintage.sh` from the cloned repo.
+This is fully self-contained — no source repo needed. It reads the
+installed manifest, removes pre-2000 cars, deletes their asset files,
+and updates the manifest.
+
+### From the source repo
+
+Same functionality via shell scripts, useful if the binary isn't
+installed yet or if you prefer scripts:
+
+```bash
+cd path/to/hypercar-colorscripts/cli
+./install-vintage.sh       # add vintage
+./uninstall-vintage.sh     # remove vintage
+```
