Same car, same day, four leads. The Marketplace message wants to know if it's still there. The CarGurus lead already knows your price is $400 over book and wants to talk about it. The Autotrader lead wants a trade number. The one from your own website has been reading your reviews for twenty minutes. Treat those four the same and you'll lose three of them.
Dealers talk about "internet leads" as one thing. They aren't. Used car lead sources each attract a different shopper, arrive in a different mood, and die on a different clock. Here's what each one actually wants, how long you've got, and what the first reply should say.
The clock, in general
Before the source-by-source part, the number that governs all of it:
higher odds of reaching a lead when it was contacted within 5 minutes rather than 30. Odds of qualifying it were 21 times higher.
Source: MIT / InsideSales.com Lead Response Management Study (2007)The gap in that study is between five minutes and thirty — not five minutes and tomorrow. Half an hour has already cost you most of it. Full breakdown in our guide to dealership lead response time.
Facebook Marketplace: minutes, and mostly tire-kickers
What they want: to know it's still available, and usually the lowest number you'll take.
The clock: the fastest of any source. Marketplace shoppers message four listings in a row and buy from whoever replies while they're still looking at their phone. An hour later the conversation is cold. A day later it's gone.
What the first reply should do: confirm it's available, give one piece of information they didn't ask for, and ask a question back. The question is what separates a conversation from a quote.
Is this still available?
Yes it is — the 2018 Rogue SV, 74k miles, clean carfax. Were you looking to come see it this weekend?
The trap: Marketplace volume makes dealers lazy with it. Copy-paste "yes, still available" replies get copy-paste results. It's the single highest-volume source most independents have, and the one where a real answer stands out most.
CarGurus: price-aware, comparison-minded
What they want: to understand your price. CarGurus publicly rates listings against its own market estimate, so the shopper often arrives already knowing whether you're above or below it.
The clock: hours, not days. These shoppers are actively comparing, usually across several dealers at once.
What the first reply should do: answer the question, then give them a reason the car is priced where it is. New tires, service records, one owner, recent timing belt. Never argue with the rating — explain the car.
The trap: getting defensive about price. The shopper isn't accusing you of anything, they're doing exactly what the site taught them to do.
Autotrader and Cars.com: further down the funnel
What they want: specifics. Trade value, payment, availability for a test drive. These shoppers are often closer to buying and more likely to be financing than a Marketplace browser.
The clock: same day, realistically same hour. They're submitting forms to several stores in one sitting.
What the first reply should do: answer the specific question and move toward a time. If they asked about a trade, ask for year, mileage and condition so you can come back with something real.
The trap: sending a payment number you haven't confirmed. Quote something you can't honor and you've bought yourself a bad conversation on the lot.
Your own website: the warmest lead you own
What they want: they're already sold on the store, or close. They've been on your inventory, probably read your reviews, and chose to contact you specifically rather than fill out a marketplace form.
The clock: they'll forgive a little more time, but you shouldn't take it. This is the lead you paid the most to generate.
What the first reply should do: everything the other replies do, plus acknowledge the specific car. These shoppers almost always have one in mind.
The trap: this is the source most dealers answer slowest, because it doesn't ping a phone the way a marketplace message does. The lead you paid most for sits in an inbox overnight.
Missed calls: the source nobody counts
Not technically an internet lead, but it belongs in the list. A missed call during a busy Saturday is a shopper who was ready enough to dial. Most stores never follow up on them at all. A text back within a few minutes — "sorry we missed you, which car were you calling about?" — recovers a surprising number.
What this looks like across a week
The one rule that covers every source
Every source wants the same two things in the first reply: something specific about the car, and a question back. The sources differ in tone and urgency, not in what makes a reply work.
Which is why trying to solve this with faster typing doesn't work. Five sources, each with its own clock, most of them firing after you've gone home. That's not a discipline problem, it's a coverage problem — the same one behind AI for independent car dealers.
How well does the industry actually do this? Pied Piper's 2026 study mystery-shopped 3,290 franchise dealerships and found 51% gave a complete answer within 15 minutes (via Auto Remarketing). Record high — and still only half, at stores with dedicated staff for exactly this.
A practical audit you can run this week
- Pull last month's leads by source. Most dealers have never looked at this split.
- Mark the time each one arrived and the time you replied. Not the time you meant to.
- Circle everything outside open hours. That's your real gap, and it's usually the biggest number on the page.
- Read your own first replies. Count how many said something specific about the car.
- Pick the worst source and fix only that one. Usually Marketplace, usually immediately worth it.
Frequently asked questions
Which used car lead source is actually worth the money?
It depends on your inventory and market, but the honest answer is that the source matters less than your response time. A cheap source answered in two minutes beats an expensive one answered tomorrow.
Should I reply to Marketplace messages that just say "is this available?"
Yes, every time, and with more than "yes." That message is the single most common opening line in used cars, and almost every dealer wastes it.
How fast is fast enough?
Under five minutes, at any hour. The MIT research shows the drop-off is already severe by thirty minutes.
What about overnight leads?
They're the majority of the problem for most independents. Either someone covers nights, or something does. Replying at 9 AM to an 11 PM lead means you were fourth in line.
Do I need a different message for each source?
Different tone, same structure: something specific about the car, then a question back. Marketplace can be shorter and more casual. Website leads can be warmer.
