You're right to dig into the records, but here's something nobody's mentioned: ask each seller specifically which services were done at a dealer versus an independent shop, then call those places to verify the 2023 Civic was actually serviced there and on schedule. A single owner's handwritten log or even a dealer stamp in the manual can be faked, whereas a shop's computer system won't lie. Once you've confirmed the maintenance is real for both cars, the multiple-owner one might actually be the better buy - it suggests the car proved reliable enough that different people didn't panic-sell it, whereas a single owner might've just decided to upgrade. Both sound solid mechanically, so pull those actual repair invoices and make your call based on verified work, not ownership count.
