Advice for buyers
What should I look for in a used BMW 4 Series Gran Coupe hatchback?
The diamond-cut alloy wheels on M Sport cars can corrode. This usually originates from kerb damage that allows road salt to react with the exposed metal. If this is left untreated, damage could spread. And since repairs to this type of alloy wheel are slightly more complex than standard alloy wheels, it can be quite expensive to fix. Make sure you’re not the one footing the bill for damage caused by the previous driver.
