A free preview from Milo. A history report shows one car's past — Milo shows the whole model: which one to buy, what breaks, and what to knock off the price.
5/10
A cushy three-row cruiser wrapped around a genuinely fragile GM drivetrain — great if someone else already paid for the timing chain job.

🎯 Negotiation ammo — walk in knowing this
Free. The seller won’t volunteer any of it.
- 💸 Budget for this: Excessive oil consumption from worn piston rings on the LFX V6 — owners report burning a quart every 1,000-2,000 miles with no visible smoke — $0–$4,500 if it goes. Check it on the test drive; if it’s near due, negotiate it down.

Which one to get — and which to avoid
✅ The one to get
A 2015 Enclave Leather or Premium trim with the 2nd-row bench, done at 60-90k miles with documented transmission fluid service and no oil-burning complaints — verify the timing chain hasn't started rattling before buying.
🚫 Avoid
Any base or Convenience trim past 110k miles with no maintenance records, especially ones with an audible cold-start rattle or a seller who says the transmission was 'recently serviced' with no receipts — that's the classic pre-failure flip.
