Spin-off show from, well yes, NCIS.
Watching the premiere episode on demand when lo and behold a silver HHR LS or LT is behind LL Cool J's new black Dodge Challenger.
It's when they come back from the commercial after the titles so the second section of the show.
Then it's gone in the next shot.

I paused it to write this so I don't know if it's a camera car that we'll see in some more of the shots or just a retro coincidence.

I noticed the car as well on NCIS-LA and later on in the week I saw a HHR on Fast Forward too!

I had seen them both also!

It actually had two shots of it, but then it just disappeared for good after that.

 

It was probably just natural traffic.

The show's watchable but it's barely a pimple on the original show's ass.
I'll keep watching to see if it gets better and if the HHR shows up again.
