I don't think these caps have anything to do with the license plate. I see no way they would fit or work to protect the screws, cap holes, reduce vibration, etc.
Maybe they are left over when the dealer installed something. Any other ideas?
The car is my wifes car. She got a four cylinder with the tech package in white with grey interior. I think this is the best version, based on reviews and features.
The dealer threw in wheel locks, front and rear mud flaps, trunk tray, and a $500 voucher for Acura assecories. (We did not qualify for the official Acura accessories deal.) All this for $650 below msrp. She got it three weeks ago and absolutly loves it.
