In a slump with a ka thump? Mr. Goodwrench says don’t be a chump!

“Mr. Goodwrench understands your GM car…”

The end of another week has come around again, so let’s wrap up our ’77-’78 thing with two spots for GM’s Mr. Goodwrench.

First, we find a driver complaining of a “ka thump” sound coming from his car. After that, multiple Mr. Goodwrench’s appear in some sort of cloning accident. Both commercials aired in September of 1978.

*Update: Thanks to YouTube viewer, wynchevy09 for letting me know Mr. Goodwrench is portrayed by actor, Barry Coe.
