"Just What I Needed" got as high as #27, so it was definitely a "hit." This station never played the Cars until "Let's Go" (from Candy-O) was released a year later.
"Let's Go" was #14...a lot bigger.
In fact, KHJ, KFI and KFRC all ignored the Cars until "Let's Go". So your hometown station wasn't alone.
Many stations held off, especially on new and unproven acts, to see if the record would crack the Top 20 in Billboard. Some wouldn't touch a record until it was Top 10...meaning they were late and held on to records that were on their way down the Hot 100.
By most standards, #27 is a stiff. From today's perspective, "Just What I Needed" clearly isn't a stiff, but we know how many LPs it sold and how well it's stood up over 31 years. A 1978 radio programmer watching the singles charts could be excused for not jumping in with both feet.
It didn't help the Cars' Top 40 airplay that their next two ("My Best Friend's Girl" and "Good Times Roll") stalled at #35 and #41 respectively....meaning not even Casey Kasem played their third single.
