Full disclosure: we make CarScout. CarGurus is a large US car marketplace, its saved-search alerts are free, and its deal ratings are useful. If most cars like yours show up on CarGurus, its alerts may be all you need.
The bottom line
Use CarGurus alerts first: they're free, cover new listings and price drops, and its app advertises real-time price alerts and deal ratings. Add CarScout if you want one daily email that checks dealer listings beyond a single marketplace, with exclusion filters and VIN tracking, and you're happy paying $5 a week for that.

The real difference: one marketplace or a market-wide watch
CarGurus alerts watch CarGurus. That's a lot of inventory, but it's one site's inventory. Its saved-searches page says it plainly: save your searches to get alerts on price drops and new listings. Its saved-cars page adds price-drop alerts for cars you've hearted.
CarScout doesn't own a marketplace. It checks MarketCheck's dealer listings for your spec about every 24 hours and emails you a digest. It checks dealer listings available through MarketCheck, so it isn't tied to any one marketplace.
If you're shopping one site anyway, CarGurus alerts cost nothing, and its app advertises real-time price alerts. We didn't measure delivery speed. CarScout is for buyers who are tired of running the same search on several sites.
Where CarGurus is genuinely better
- Free. Saved-search alerts don't need a subscription.
- Speed. CarGurus advertises real-time price alerts in its app. CarScout sends one email a day.
- Deal ratings. CarGurus compares asking prices with its Instant Market Value and labels deals from Great to Overpriced, where a rating is available. CarScout shows price versus an average in some digest entries, but it doesn't rate deals.
- Private sellers and an app. CarGurus includes private-party listings and has phone apps. CarScout covers dealers, on the web.
What CarScout offers
- Not tied to one site. Your scout checks dealer listings available through MarketCheck in one daily email. Keep marketplace alerts that add useful results.
- Exclusions. Rule out colors, transmissions, drivetrains, or keywords so the digest only contains cars you'd consider.
- VIN scouts with wildcards. Follow one car, or a VIN pattern, next to your spec searches.
- No marketplace in the middle. CarScout is paid by buyers, not dealers. That doesn't make its matches better, but it means nothing in your digest is a sponsored placement.
Who should pick which
| You are | Pick |

| Tired of irrelevant matches | CarScout, with exclusions |
You don't have to choose. Keep a free CarGurus alert running, use its deal ratings to judge price, and let a CarScout scout catch dealer cars listed elsewhere.
FAQ
Are CarGurus alerts free?
Yes. CarGurus saved searches send alerts on new listings and price drops, and saved cars get price-drop alerts. You don't pay for either.
Is CarScout faster than CarGurus?
No. CarScout checks each scout about every 24 hours and sends one daily email. CarGurus advertises real-time price alerts in its app.
Does CarScout include CarGurus listings?
CarScout watches dealer listings through MarketCheck, not through CarGurus. Many dealers list the same car on several sites, but we can't promise any specific listing appears in both.
What are CarGurus deal ratings?
CarGurus compares the asking price with its Instant Market Value, an estimate built from comparable listings, and factors in dealer reputation. It's guidance, not an appraisal.
Can I track one specific car with CarScout?
Yes. A VIN scout follows one VIN, or a wildcard pattern, and its price drops show up in your daily digest.
Try CarScout
If you're running the same search on CarGurus and two other sites, set up one scout instead. It's $5 a week, and it emails you once a day.
