It isn't the workers, as much as a rather stale brand, IMHO. They can leave Manny, Moe, & Jack in the board room, behind closed doors. Start with a new name, logo, promote the selling of parts for later model cars, i.e., a more modern company. I believe that this is all it would take. I think image is nearly everything in this case. After all, the products sold are virtual commodities. It might take a few years to kick into gear but they've got the sector, locations, product lines, etc. I mean, where was Autozone 10-15 years ago. I remember when the stock was $26. I obviously made a mistake not buying it, but that's the way it goes. PBY can still compete but they've got to work on the old image, IMHO.
I actually don't think PBY can compete are parts, at least not the DIY area, as AZO and Advance swamp them in volume and PBY really can't make money competing on price.
I like the strategy of moving towards tire & service centers. Let's face it, with margins on tires around 30%, but the service and add-ons (wheel balancing, valve stems, alignments) all being pretty much profit, it's a solid market.
Maybe down the road they'll try and re-address parts, but for now I think they're on the right path with the tire and service model.
