The car's owner, who doesn't want to be identified, said the car had just been delivered to him that day. He only had the classic car in his possession for four hours before thieves nabbed it.
"The first thing I thought was maybe a tow, but then reality sunk in," the owner said.
As a surveillance video shows, the thieves weren't very bashful.
"People are walking in and out of the establishment and he gets right into the car," the owner said.
Shortly after that, suspect number two slid under the Impala to try to get the car to start. That didn't work either.
On the pair's third attempt, they pop the hood, get the car running and were off.
The owner said it was more than just rubber and steel being driven away.
"Right now there are two of them in the classic antique auto trader for $99,000 dollars," he said.
The car was parked behind a billiards club in downtown Glendale. A car show was going on outside and the Impala's owner stopped by the club to grab a drink. The suspects dropped in as well. A security camera snapped some pictures of them.
Glendale police are waiting to see if someone may recognize the pair and give them a call.
In the meantime, the car's owner has set up a hotline and is offering a $5,000 reward for the return of the Impala. He's worried the Roman red classic car will be dismantled and sold for parts.
"These types of vehicles are put in a boxed container, and they are shipped across to Japan and Australia," he said. "In Japan, these cars bring in in the neighborhood of $150,000 as the car sits."
The question is: where does it sit right now? You may not be able to recognize the suspects, but if they're out joyriding, it wouldn't be too hard to spot this car.
The car has a white convertible top and plaid interior. It has Tennessee plates, 091WDZ.
"You're not going to see many Roman red 1959 frame off restoration convertibles driving around," the owner said.
But if you do, there could be $5,000 in it for you.
Anyone with information about the stolen car is asked to call the Glendale Police Department at (818) 548-3127.
