2015 Audi A4 vs 2015 BMW 535d
Two luxury sedans, compared on what actually matters when you're buying used:
what breaks, when it breaks, and what it costs you.
2015 Audi
A4
6/10
Buy it for the chassis and interior quality, budget for it like you're dating a Bavarian accountant who bills by the hour.
VS
2015 BMW
535d
6/10
738 lb-ft of torque and 45+ mpg on the highway, wrapped in a car that will eventually make you fluent in swirl flaps, EGR coolers, and injector seals.
Dead heat: both score 6/10. The tiebreaker is which specific car you find.
