You know all those advertisements that claim BMW vehicles are cheaper to maintain than its German competitors? We’re not saying that’s a lie, but YourMechanic has the BMW 328i in second place with a cost of $15,600 to maintain over 10 years. But perhaps what’s even more telling is that BMW is the most expensive automaker to maintain with a cost of $17,800 – that’s $4,900 more than second-place Mercedes.
