I can relay my experience. I had a 70 Challenger RT that was fully restored in B7 blue and a B3 blue 70 Charger.
The 70 Charger was a people magnet. It drew crazy attention. The Blue Challenger, not so much.
At another time I had a White TA and a Sublime Challenger. The sublime car drew all the attention.
So I concur with a lot of the previous comments. The Charger is so recognizable to many and hi impact paint just adds to the allure.
Personally, i would take your White / Black color scheme any day of the week. I love the combo. I should have never sold my T/A !
You have some awesome cars, enjoy them both
