I've had my car in several shows and come home with several trophies.
Judges look for "UNIQUENESS"! (but always in good taste).
Here are some things that make the judges say "WOW!"
1. An immaculate engine bay, including treated belts, hoses and all rubber and plastic.
2. Super clean suspension (springs, shocks, calipers, rotors, etc.)
3. Anything a little unique, but in very good taste. (For example, certain engine parts painted to match the vehicle).
4. Perfectly detailed tires.
5. Judges will do the "white-glove-test" Make sure that areas that a normal person would not see are detailed. Those are the areas that judges look for. (Example. The hood hinges and hood struts. Judges love to get their fingers down in there!)
6. Make sure your interior has nothing in it. (no coats, toolboxes,cell phones, etc.) And the seatbelts are neatly in place.
7. Be sure to straighten the A/C vents so they are lined up. It makes a difference.
8. Detail the door jambs.
