Here’s something I wish I’d known when I was selling cars.
We looked at 106,507 retail deals across 53 dealerships over the past year, across a mix of brands. Four out of five had no connection to the store’s own service department. The buyer hadn’t been in for service in the year before the sale, and the trade-in hadn’t come through the service lane either. Even when we counted family members who share a phone number or email, three out of four deals still had no service connection.
Sales and service share a building, a name on the sign and a customer list. Most of the time, they don’t share the customer.
Service is where the next sale starts
We then followed 19,374 retail buyers from early 2023 for three years. First we counted how many times each one came back for service in their first year. Then we watched who bought another vehicle from the same store over the following two years.
- Buyers who never came back for service had a single-digit chance of buying from that store again.
- One service visit made a buyer 60% more likely to come back.
- Buyers who serviced with the store at all were twice as likely to buy their next vehicle there.
- Buyers with four or more visits in year one were three times as likely.
Every added visit raised the odds. And this wasn’t a few strong stores pulling up the average. At all 24 dealerships, buyers who serviced came back to buy more often than buyers who didn’t.
Nearly half your buyers never come back
The hard part is that 43% to 49% of those buyers never returned for service in their first year, depending on how strictly you match records. Nearly half of every month’s deliveries leave the lot and become the group least likely to buy from you again.
The used side is where it shows most. About 29% of new-car deals had a service connection, compared with only 13% of used-car deals. More than 4 in 5 used buyers have no relationship with your service department on the day they buy. A used buyer is often a first-time customer at your store, so they’re also the one with the most to gain from a proper introduction.
This is an execution gap, not a market gap
Across the 53 stores, the share of deals connected to service ran from 3% at the low end to 40% at the high end. The middle store sat at 24%. These are similar stores with similar customers. Much of the difference is what each store does between delivery and the first oil change.
What a real service walk looks like
A service walk is more than pointing at the service drive on the way out. It’s a short handoff that gives the customer a reason to come back:
- Walk them in and introduce a person. Shake hands with an advisor and use the advisor’s name. A name and a face give the customer someone to call, which a phone number on a key tag can’t.
- Book the first visit before they leave. Put a date on the calendar, not just “see you in 5,000 miles.”
- Follow up before that visit is due. The first visit is the one that counts most. In our data, a single visit is what moves a buyer from a single-digit chance toward twice the odds.
- Treat used buyers the same as new. They have the weakest tie to your service department today and the most room to grow.
- Let VehicleLyfe encourage your new buyers for you. This is the easiest solution! #slightbias
You’ll want to know whether it’s working. Check the share of last month’s buyers who came back for service within 90 days, and check again a year later.
Loyalty is on the horizon, and for most of your buyers it starts in the service lane.
Methodology
Data comes from VehicleLyfe’s DMS records. The first finding covers retail deals finalized July 2025 through June 2026 at 53 rooftops with complete sales and service data for all 12 months. A deal counts as connected if the buyer had a closed repair order at that store in the prior 365 days, or the trade-in VIN was serviced there in that window. The repurchase finding follows individual retail buyers from January–June 2023 (one deal per buyer, fleets excluded) with unbroken data through June 2026. Service visits in the first 30 days after delivery were not counted, so delivery and PDI work doesn’t inflate the results. Everything is matched at the same store only: a customer who services or buys at a sister store in the group counts as gone, which means the real numbers are higher than what we print. These figures show that service and repeat purchases go together. They don’t prove that one causes the other.
