🎯 Negotiation ammo — walk in knowing this
Free. The seller won’t volunteer any of it.
- ✅ Verify this recall: Rear exhaust pipe/muffler rust-through (Southeast/salt-belt cars). Make the seller prove it’s been done — an open recall is money off the price.
- 💸 Budget for this: Frame corrosion at rear crossmember and body mounts (Northeast/rust-belt) — $0–$8,000 if it goes. Check it on the test drive; if it’s near due, negotiate it down.
- 🧾 Your opening line: “2014 Toyota 4Runners 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
2014 Trail Premium with KDSS, rear locker, and the sliding rear cargo deck — ideally a Southern/Western truck with a clean frame and under 130k miles. If you can find a real 2014 TRD Pro (first year), buy it and never sell it.
🚫 Avoid
A Northeast/Midwest Limited on 20s with no service records and visible surface rust on the frame rails — you'll spend $2k on tires, another $3k chasing suspension, and worry about the frame the whole time.
