Thank you everyone, for the good feedback.
We tend to look at our cars through rose-colored glasses, I think. The reason for the fake vent ports was attending my first 300m Club meet and feeling very plain with no mods...so I rushed out and hastily slapped them on. I sort of liked them, but recently realized that since I thought they looked cheap and crappy on other cars, they probably didn't look good on mine either!
The letters were a good thought, just not done right. If one could get a graphic of the logo done well it might look pretty good.
