Quoted from Underspin:
Automakers keep tight price controls on their distributors via MSRP. Stern needs to do the same.
I still don't understand the "need" to fix prices, "desire" is a better word. Would Stern's products be thought of as lesser quality if they sold at $4200 vs $4700? No...they have literally no outside competition at that price point. The only competition going on is amongst distributors, so this pricing floor appears to be driven more by some distributors begging Stern for minimum profit margins to offset competition pressures.
