Police are investigating whether the fire was intentionally set.
"We are out here, flames are shooting up like crazy, so we grabbed garden hoses and are hosing down our garages and everything to prevent it from spreading," said Richard Sypniewski.
Ty Hanson and his wife lost their Jeep and 1975 Stingray corvette they were rebuilding. The fire from the neighboring garage apparently jumped to theirs.
"I thought maybe some kids or something were shooting off firecrackers are something," Hanson said.
Juan Vazquez was clipping away the debris on two of his garages.
"I do not have as much to do as other people but call insurance, pay my deductible," he said.
