UPDATE: In a comment below Claudia mentioned that Jarvis Jeep had a very catchy jingle: Beep Beep Jarvis Jeep. Apparently, that jingle was played a lot in Oregon as a variety of folks from Oregon have mentioned it on the internet. I tried to find a commercial with jingle, but no luck. Also, at one time Jarvis Jeep was the largest jeep dealer in the nation. If I’d realized Robert Jarvis was still alive I’d have tried to contact him. Unfortunately, he passed away this past April.
Apparently, he was quite the character and boxer. According to the article in this magazine, during a boxing tournament in 1946 Rocky Marciano broke his hand on Bob’s head. After which, they became life long friends. (go here to learn more and then search for ‘Jarvis’.)
Here’s an image with the jingle on it that was posted on pinterest:
Craig scanned this from the January 1959 issue of Jeep News. It features the Jarvis Jeep dealership from Portland, Oregon.
