what are they trying to say?

Very near my house is a car mechanic shop. The shop has a company car, which is usually parked on the street outside.
The car, like company cars everywhere, has the name of the shop written on the side. But it also has decals simulating bullet holes all along the side of the car.
I don't know what message this is trying to send. Are they implying their service is so good, competitors try to gun them down? Are they trying to make me think the shop is a front for a shady criminal organization? Are they simply gun enthusiasts?
And would any of these possibilities make me more likely to take my car to this shop, rather than a shop which doesn't want me to think they are often dodging bullets on the street?
