There were two out right lies that they told their salesmen in this film. 1, it claimed they were the only full sized brand that offered two distinctive 2 door hardtop roof styles, that wasn't True, Ford and Plymouth both offered two different 2 door hardtop styles on the Galaxie and Fury. Additionally, it claimed that the locking steering wheel and transmission shifter anti theft device was exclusive to Chevy. That too wasn't true, it was a Federal Standard that was promulgated for 1969......boy, oh boy, such fibs!
The 69 and 70 fullsized chevies were very clean attractive cars. The exception being the awkward proportions of the custom coupe roofline. One unfortunate aspect of the 69 and 70 was the cheapening of the dashboard. This happened across all full and midsized GM cars in 69. Chromed metal was replaced with cheap flimsy plastic trim. It also created all kinds of electric glitches due to grounding issues related to the plastic bezels requiring ground straps and stripped plastic studs that loosened nuts. A shame because they were otherwise great models.
