If you didn't feel a vibration in the steering wheel or the car then you could leave it as is. I have not had good luck repairing bent wheels. Did it once back in the day and they just bent again... I would go to one of the OEM BMW parts venders found here in the sponsor classified to find the best price on replacement wheels. ZCP wheel are around $500 ea. The dealer will rip you off.
