I think this might be the relevant change (contained in bill S-1 which was substituted in the Regulatory Reform Committee):

"2 (i) Sell any new motor vehicle directly to a retail customer 3 other than through <del>its</del> franchised dealers, unless the retail 4 customer is a nonprofit organization or a federal, state, or local 5 government or agency. This subdivision does not prohibit a 6 manufacturer from providing information to a consumer for the 7 purpose of marketing or facilitating the sale of new motor vehicles 8 or from establishing a program to sell or offer to sell new motor 9 vehicles through the <del>manufacturer's</del> FRANCHISED new motor vehicle 10 dealers THAT SELL AND SERVICE NEW MOTOR VEHICLES PRODUCED BY THE 11 MANUFACTURER."
