Stories from the shop
Direct rivals running close enough that you'd be fine either way. Reliability scores within rounding distance (3.4 for the 2011 Audi A6, 3.2 for the 2011 BMW 328i). When two vehicles in the same segment land this close, the data alone won't pick a winner.
Going with the 2011 BMW 328i? Watch the engine and electrical. The 2011 Audi A6 has fewer reports in those categories, so you'd be trading one set of weak spots for another.
On the dollars-and-cents side, total repair exposure across the top problem areas runs 10.5x higher on the 2011 BMW 328i. That's the number to keep in mind when you're pricing the deal — a $2,000 difference in purchase price disappears the first time you're staring at a transmission rebuild.
Bottom line: pick based on use case more than the spec sheet. If you tow heavy and don't want to think about it, that's one calculation. If you're a daily driver and want the cheapest path forward, that's another. Both of these will get you down the road. We're just telling you where each one is most likely to break.

Which has more recalls?

Is an extended warranty worth it on either of these?
Both vehicles are out of factory bumper-to-bumper coverage at this point. Combined repair exposure across the top problem categories runs around $11,500 on the higher-risk vehicle. A quality service contract typically costs $1,800–3,500 over 3 years, so a single major failure usually pays for the contract. The math favors warranty coverage on whichever vehicle you choose, especially if you plan to keep it past 100,000 miles.
