Owner Barrie Crampton has uploaded footage taken on April 17 of a youth loitering on the forecourt. Later that day, wheel trims were stolen from several vehicles.
Crampton said: "I am fed up with coming to work to find I am £100 down before I have even started. It isn't fair. I, like other victims of crime, work hard for a living and don't expect to pay out to put people's wrongs right."
He hopes putting the footage online may help loyal customers recognise the suspects. Earlier this year the site's CCTV system recorded drunken youths causing £300 damage to two vehicles' bonnets.
Crampton has added his videos to Youtube which can be seen here.
