🎯 Negotiation ammo — walk in knowing this
Free. The seller won’t volunteer any of it.
- 💸 Budget for this: Rear subframe, brake lines, and fuel lines corroding from road salt exposure — this is the defining W212 issue and the source of most serious NHTSA complaints — $3,000–$9,000 if it goes. Check it on the test drive; if it’s near due, negotiate it down.
- 🧾 Your opening line: “2014 Mercedes-Benz E-Classs 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 2014 E350 4MATIC Sport sedan, southern/dry-state car with full service records and documented subframe inspection — the AWD V6 combo is the reliability sweet spot and 4MATIC adds real resale appeal.
🚫 Avoid
Any rust-belt car without documented undercarriage inspection, and be wary of the E550 if you're not ready for turbo/direct-injection maintenance bills.
