Theres no way you could survive selling 1 of anything, unless maybe your Toyota. Nearly every dealership in the country is multi franchised. They may not share the same site but they are all part of a larger group.
Its also a lot tougher for dealers to make money out of finance / insurance products now. I can see a rationalization of dealers across many brands in the coming year or so. I think early 2019 will see a bigger sales hit as manufacturers like Holden have been furiously registering demos to keep their numbers looking good, they cannot sustain it for much longer. Ford has also had dealers registering as many demos as they can so they can advertise them online. To advertise a car it needs to have 1500 kms on it. This will affect them sooner then later as they will run out of room to keep registering cars.
I can see Dec and Jan being a bad month for Ford.... Theres been a huge issue with Ranger plant changes which has put some cars back 2 months...
Every dealer in my region ALL multi franchise(except the Toyota dealership)It is becoming the norm now.The Holden dealer that my local Ford dealer now has,if it goes under,he has a lot of other brands around him to survive.Really think he is game taking it on,or,knows something nobody else knows.
