Had they been in the Trophy font (like these PH-Quick wannabe's ) I'd say take them off but the font you used makes it clear you're having a laugh about it
The first owner of 298 removed the side skirt logos and I bought the car without even noticing! Not really very important, people who know about cars know it's a Trophy, people who don't couldn't care less and probably think it's an aftermarket sticker anyway.
