Advice for buyers
What should I look for in a used BMW 3 Series hatchback?
The diamond cut alloy wheels on M Sport cars can corrode. This usually comes from from kerb damage that allows road salt to react with the exposed metal surface. If this is left, it could allow the damage to spread, and since repairs to this type of alloy wheel are slightly more complex than normal alloy wheels, it can be quite expensive to fix. Make sure you’re not the one footing the bill.
