Lincolnshire used car dealership NLS Trade Direct has closed, citing vandalism as the final straw.
Owner Jim Lee said the final blow was dealt to his struggling business in Lincoln when a third of his stock was damaged.
He arrived at work on Sunday to find his office ransacked and nine of the cars broken into.
All the damaged vehicles were parked in the forecourt of his premises in Dixon Way, Lincoln.
"It has been a very hard time in the trade and this was a push too far. I don't think the culprits would care that they put me out of business," he said.
