The time period for this show is the early to mid 2000's, yet a Kia Soul is seen when Jimmy answers the phone while walking in the city. The Kia Soul didn't release until 2008, and the Kia Soul appears to be of the color green and body style released on or after 2014.

When the scene appears of Jimmy in his father's corner store, Jimmy peeks around a shelf housing cans of 'P$$T' cans. Although the scene is a flashback, taking place in the 1970s, the P$$t! brand was only introduced in 2015 as a Kroger store brand.

When Jimmy is sitting at the signal light watching the inflatable man, he gets honked at by the car behind him. When he looks at the car, it is a Chevy Sonic, which didn't debut until 10 years (2012) after the events of Better Call Saul.

At the conclusion of Jimmy's inflatable tube man reverie (after the motorist behind him honks) there is audio of his car accelerating up to cruising speed, but the video shows it's merely idling forward.
