The junkyard offered $920 before we finished describing the car. The Facebook Marketplace buyer who eventually paid the most offered $1,340, but he arrived on day 11, lowballed twice before that, and we spent 4.5 hours fielding messages and running two in-person showings before the deal closed.
We ran this test on a 2015 Chevrolet Cruze with a confirmed cracked head gasket and 148,000 miles, tracking every contact, offer, and time expenditure across 14 days on both channels simultaneously. The $420 difference between channels was real. So was the cost of earning it.
1. The Test Vehicle and Disclosed Condition
We disclosed the head gasket failure in full on every channel. No concealment. The car started and ran, idled normally, and drove under its own power for short distances before coolant loss became a concern. Exterior: minor door dings, two paint chips on the hood. Interior: above-average for mileage. No warning lights except the coolant temp and the CEL from a P0300 misfire triggered by coolant contamination in cylinder three.

2. Junkyard Offers: Day 1 Through Day 3
We contacted four junkyards on day 1. Three responded same day. One requested a photo inspection before quoting and came back on day 3.
Yard | Quote ($) | Response Time (hrs) | Pickup Window | Condition on Quote |
|---|---|---|---|---|
Junkyard A (national buyer) | $850 | 0.5 | Within 48 hours | Phone quote, VIN check only |
Junkyard B (regional) | $780 | 1.5 | Within 24 hours | Phone quote, no VIN check |
Junkyard C (regional) | $920 | 2.0 | Within 72 hours | Phone quote, requested one photo |
Junkyard D (local) | $760 | 26.0 | Within 48 hours | Requested photo inspection, day 3 response |
Best junkyard offer: $920 from Junkyard C, confirmed on day 1, pickup available by day 3. Time invested to get this offer: 22 minutes of phone calls total. Zero in-person meetings required.
3. Facebook Marketplace: All 14 Days Logged
We listed at $1,800 as-is, disclosed the head gasket fault in the title and the first line of the description, included 11 photos. We did not hide the fault to generate traffic and then disclose later. The asking price was above market for a broken Cruze, intentionally, to leave room for offers.
Day | Activity | Offer ($) | Outcome |
|---|---|---|---|
Day 1 | 4 inquiries, 2 asked if head gasket was confirmed | None | No offers |
Day 2 | 1 offer via chat | $400 | Declined (lowball) |
Day 2 | 1 offer via chat | $600 | Declined (below junkyard floor) |
Day 3 | Offer from car flipper, in-person inspection requested | $900 | Declined, below $920 junkyard offer |
Day 5 | Offer from independent mechanic, no inspection requested | $1,050 | Counter-offered at $1,200, no response |
Day 6 | 2 inquiries, no offers, 1 asked if car was still available | None | No offers |
Day 7 | Offer via chat, no explanation | $750 | Declined |
Day 9 | Offer from buyer who wanted the 1.4T engine for a swap | $1,100 | Counter-offered at $1,250, buyer went silent |
Day 10 | 1 inquiry, asked for compression test results | None | No offer after we disclosed no compression test done |
Day 11 | Offer from mechanic, inspected same day, bought same day | $1,340 | Accepted |
Day 14 | Car sold day 11, listing closed | N/A | Transaction complete |

4. Time Cost: What the $420 Difference Actually Required
The junkyard transaction required 22 minutes of phone calls and zero in-person time. The marketplace transaction required substantially more.
Activity | Time Spent (min) | Day of Test |
|---|---|---|
Writing listing and uploading 11 photos | 28 | Day 1 |
Responding to 14 chat inquiries over 14 days | 62 | Days 1-14 |
In-person showing for day 3 flipper (drove to car, waited, showed) | 45 | Day 3 |
In-person showing and inspection for day 11 buyer (drove, waited, showed, negotiated) | 70 | Day 11 |
Fielding repeat follow-ups from declined buyers | 18 | Various |
Total marketplace time investment | 223 min (3 hrs 43 min) |
At $420 net gain over the best junkyard offer and 223 minutes of time invested, the marketplace premium worked out to $113 per hour of active effort. That number is favorable for most sellers. It shifts unfavorably if the buyer pool produces more showings, more lowballs, or a later close than 11 days.
5. What Failed in the Marketplace Channel
The compression test request on day 10 ended a potential offer. We had not run a compression test before listing. The buyer wanted confirmation that only cylinder three was affected and the remaining three cylinders were within spec. Without that data, they declined to offer. A compression test on the 1.4L LUV takes approximately 20 minutes and costs nothing if you own the tool. Cylinder-specific compression data would have answered that buyer and potentially produced an offer 24 hours before the day 11 close.
The day 5 mechanic who went silent after our $1,200 counter was the highest-value buyer we did not close. His $1,050 offer was $130 above the eventual sale price when adjusted for the time difference. If we had accepted $1,050 on day 5, the transaction would have closed six days earlier.
Three inquiries asked whether the head gasket crack was external or internal to the combustion chamber. We had a combustion gas test confirming positive result but no block test confirming whether the crack sourced from the head, the block, or the gasket itself. Buyers capable of paying $1,100 or above on a broken car wanted mechanism-specific data, not just a positive combustion test result.

6. The 14-Day Cash Comparison
Channel | Best Offer ($) | Close Day | Time Invested (min) | In-Person Meetings | Net per Hour of Effort ($) |
|---|---|---|---|---|---|
Junkyard C | $920 | Day 1 (pickup day 3) | 22 | 0 | $2,509/hr |
Facebook Marketplace | $1,340 | Day 11 | 223 | 2 | $113/hr |
Difference | +$420 marketplace | +8 days | +201 min | +2 meetings |
If the car runs, has a clean title, and has a diagnosable fault rather than terminal mechanical failure, Facebook Marketplace outperforms the junkyard on price. The junkyard is faster by 8 days and requires no showings. The marketplace premium of $420 on this vehicle required 3 hours and 43 minutes of active effort across 11 days.
If your time is worth more than $113 per hour, take the junkyard offer on day 1. If the car does not run, cannot be driven for a test drive, and has no specific component a buyer wants, the marketplace premium compresses significantly and the junkyard offer closes faster with zero time overhead.
