Beautiful build!
And, please take the following comments as purely constructive ... that's how they are offered.
A new car on the transporter would be bare-wheeled with the hubcaps in the trunk.
A 440 would have backup lights. I can't tell clearly from your pix, but it looks like you chromed the backup lights (the rounds above & inboard from the taillights). They would look more whitish-clear. As I say, I can't tell well on my computer monitor if you did that, so forgive the comment ... but a LOT of builders of '62 Darts leave the backup lights chrome as if they were trim embellishments.
Darts in '62 had whitish-clear parking light lenses (under the grille), not amber. They came from the factory with clear bulbs, but many owners replaced the OEM bulbs with amber tinted bulbs when the amber-turn-signal trend came into full bloom in '63.
Finally, an item most '62 Dart builders miss: The inner rings of the headlamp bezels were white. Very predominately white. The outer surfaces were chrome, but there were inner rings/inserts that were white. See the pic below.
And I agree with Harry . . . the untreated license plate engravings make your model less realistic in appearance. The 1:1 had no engraving, just flat metal brackets in the rear and mounting holes in the front.
Having said all that ~ for edification, not criticism ~ it's your model and a beauty at that. Detail it as you wish, and as a former owner of a '62 Dart, I love to see them!
