The down economy has forced one car shop in Lehigh County to think outside the box.

Apparently hot rods aren't selling anymore so enter the "zombie apocalypse vehicle".

To take a line from a popular movie, mechanics at Sour Apple Auto in Coplay, Lehigh County are working Fast and Furious.

"It was a hard transition to begin with, but it kind of turned into a fun project," said Joseph Berrocal, owner of Sour Apple Auto and Customs.

The shop is known for restoring muscle cars and hot rods.

A down economy has forced Sour Apple to change its business.

"They don't have $40,000 to $50,000 to spend on a Chevelle or Nova or something like that," added Berrocal, "These cars are just as quick, sometimes quicker than the old muscle cars."

So the guys are restoring a Hyundai Tiburon complete with LED lights and nitrous oxide.

"It just kind of came about that we decided to do a zombie truck," said one mechanic.

That's right, the guys are turning a jeep into a zombie apocalypse-fighting machine.

"It's got a full cage. It's going to be fully functional. It's going to go up a couple of more inches. Little bit bigger tires," said Berrocal.

Once the suspension is installed and the new paint is finished on the vehicle, there's only one thing left to do on a zombie apocalypse car. That's arm it.

"We can't put real guns on it, but we're putting air soft guns on it," added the creator, "It's going to have an AK-47 on the roof. It's going to have some handguns off the roll bar and stuff."

The group will have the vehicle done by October and then look for it on a road near you.
