🎯 Negotiation ammo — walk in knowing this
Free. The seller won’t volunteer any of it.
- ✅ Verify this recall: Side Blind Zone Alert / rear sensor module failures throwing 'Side Detection System Unavailable'. Make the seller prove it’s been done — an open recall is money off the price.
- 💸 Budget for this: 6T75 transmission harsh shifting / torque converter shudder — $2,000–$3,500 if it goes. Check it on the test drive; if it’s near due, negotiate it down.
- 🧾 Your opening line: “2015 GMC Acadias have known issues around this mileage — here’s my number.” Milo’s full report hands you the market price and a line-by-line offer script.

Which one to get — and which to avoid
✅ The one to get
A 2015 SLT2 or Denali AWD with full service records showing a documented timing chain/water pump job or under 60k original miles — these are the sweet spot before major wear items hit.
🚫 Avoid
A high-mileage (120k+) base SLE-1 FWD with no maintenance records and a cold-start rattle — that's a transmission and timing chain bill waiting to happen.
