Dart Lite Resto (sorta, kinda..)

Locomotion said
Dart Lite was 1976 only option package along with Feather Duster.

Exactly. It was an economy stab on its last year. I believe both were rated at 34 hwy/26 city. Lizzie was still getting 30mpg back at 100k miles.
The best numbers say
1500 Dart Lites
3000 Feather Dusters
(Approximately)
