I quite like the idea of down badging,
don't forget to tell the insurance though., Even though your using something that makes the car less desirable alot of insurances will see this as a modification and its not unheard of for insurers to refuse payouts due to exterior mods that have not been mentioned.
Also worth noting, Modified insurance can often be cheaper than standard.
My LCR policy went down over £200 by switching from standard to modded insurance and one of the qeustions I was asked was ' have you added or changed any stickers or badges'
