I've noticed that LS-equipped cars often end up gravitating towards each other anyway, be it at car shows or just recognizing each other on the street. If you want to say that you're affiliated with the family of LS-cars, then why not slap a LSx badge on there and boast that? I couldn't give a **** less. The people that get worked up about this stuff are a special breed of stupid.
Frankly, I'm debating "ITSAV6" for my license plate, so take my 2-cents for what that's worth
