M5? Great example, Thanks. $120k vehicle that burns oil at a rate(1 qt every 500 miles) that's acceptable to BMW but not to any smart person. They blow rod bearings rendering the engine destroyed and $35k to replace it. This car is completely stupid. Super expensive brakes (2500 per axle)that wear out every 35k miles, Slow compared to my car (My '16 P100D destroys the M5 in a drag race and I can seat 7!), poor gas mileage, heavy, and super expensive to maintain. Has a nice interior though
A common story, 29,000 miles, oil condition sensor(measures oil level) goes bad and give zero notice of this, the vehicle does not have a dipstick to check oil level. Oil reaches damaging level within the miles recommended between oil changes and voilà. Anyone who buys one new is rich enough not to care about this because they will get rid of it by 25k miles. From there it's a cliff of depreciation and a mountain of expenses.
