🎯 Negotiation ammo — walk in knowing this
Free. The seller won’t volunteer any of it.
- 💸 Budget for this: Multitronic CVT mechatronic unit / valve body issues on 3.2 FSI cars (Tiptronic on V8 is sturdier) — $2,000–$5,000 if it goes. Check it on the test drive; if it’s near due, negotiate it down.
- 🧾 Your opening line: “2008 Audi A6s 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 2008 A6 4.2 V8 quattro with Tiptronic (not the 3.2 FSI/Multitronic), full documented timing chain and coolant system service history, and no air suspension faults — ideally a one-owner car with Audi dealer or VAG-specialist records.
🚫 Avoid
Any 3.2 FSI Multitronic car with unknown transmission fluid history, or a low-mile 'garage queen' that's actually been sitting — rubber seals and plastic cooling components deteriorate with age regardless of mileage.
