Ours are Powerhouse too, except they include car sales. Honda took all the independent dealers ( some were Atv only, others were mixed small engine) and offered it to the local auto dealer.
I was told Honda did this to increase "the Honda Experience" and have all honda under one roof. Small towns that once only had a Honda small engine dealer, now have nothing. How this helps Hondas bottom line and image i dont know.
The only thing its done it tick off consumers. I have lots of Hondas, and the policy with the Powerhouse, is to not stock hardly ANY parts. Everything is shipped from a warehouse. Its usually only a day or 2 out, but the independent dealers always had stock.Its a PITA when your in the middle of something and need a part.
Also ive noticed the prices have gone higher. No competition.
