2015 BMW 535d vs 2015 Mercedes-Benz C-Class
Two luxury sedans, compared on what actually matters when you're buying used:
what breaks, when it breaks, and what it costs you.
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.
VS
2015 Mercedes-Benz
C-Class
5/10
Gorgeous, quiet, and surprisingly fun for a 'baby S-Class' — but check the rear subframe before you check anything else, because that's the one that can kill you, not just your wallet.
Milo scores the 2015 BMW 535d higher — 6/10 against 5/10.

✅ 2015 BMW 535d
A 2015 535d xDrive with M Sport package, full BMW dealer service history including all three diesel recalls completed, and documented injector/EGR work if it's past 100k miles — this is the sweet spot of torque, comfort, and (relative) reliability confidence.
