It's only a dealership isn't it?
Wouldn't think it's a huge financial deal, probably cuts down on finances being spent by the club more than anything as I'm sure that they would provide company cars for the Manager and coaches if required.
A Mazda dealership used to do this back in the 80's for the club. Maybe a few local businesses are seeing something behind the scenes that is encouraging them to get involved again. There are one or two others that have previously had their fingers burnt who are coming back into the fold as well.
I remember the Mazda thing in the 80's. I'm sure they had a back page advert on the programme for at least one season.
