Which one to get — and which to avoid
✅ The one to get
A 2015 A4 3.0T Quattro Premium Plus with the Bang & Olufsen and Nav package — full documented dealer service history including oil consumption checks, walnut-blast records if 2.0T-adjacent work was ever done.
🚫 Avoid
A high-mileage base 2.0T FWD with spotty maintenance records and no proof the oil consumption issue was addressed — that's a ticking time bomb toward a $2,500+ engine job.
