Damaged alloy wheels can hit you in the pocket!
Damaged alloy wheels, apart from making your car or motor bike look scruffy while you own it can also hit you in the pocket when it's time to more on. If it's your vehicle and you want to sell it privately or through trade and it has untidy or corroded alloy wheels this can significantly affect it's value.
Whether you lease or own
Even if you don't own your vehicle, and lease it instead, you'll be penalised at the end of the lease term. The first thing a vehicle inspector notices when they assess your vehicle at the end of a lease are the wheels. If they are damaged you'll end up paying for them anyway, possibly to the full value of a replacement set of new wheels.
