Someone slashed the tires on dozens of vehicles at six different parking lots along West Street Road in Warminster.
Surveillance video from Lafferty Chevrolet shows what appears to be one person meticulously going between their fleet of trucks.
The suspect targeted at least 37 trucks and slashed 99 tires.
"It was done very quickly - only 3 or 4 minutes, if that," said Joe Taber of Lafferty.
The video shows one suspect, but police are ruling out the possibility that more are responsible.
The price tag in damage at Lafferty is more than $20,000.
York Road Auto Glass's parking lot had seven vehicles with tire damage.
"I'm going to pay for the ones in my lot, yes," said York's Bill Primose. "I can't tell a customer, 'Your car was left here for work. By the way, you need four tires.' It has to come out of my pocket."
Up and down Street Road at least six businesses were affected.
Coffman's Service is another one, as is Tires Plus.
At Hertz Rental and Sales they discovered the damage Saturday morning, and the on-site auto service shop had to work quickly.
"A big inconvenience, especially if the car is sold and the customer is put off buying it," said Robert Montgomery.
The vandalism happened between midnight and 4 a.m.
Warminster Police say they continue to receive calls, and they are continuing to gather complaints. So the number of victims is expected to rise.
They are asking anyone with information to reach out to them.
