I recently found out that the Australian mattress brand, Peace Lily has a 365 Day Honest Price Policy where they don't offer sales or promotions (other than a friend referral reward of $50 for select purchases) so you never have to worry about chasing the best price with them.
I understand Mercedes-Benz also has a fixed-price, direct-to-customer agency model.
What other brands only offer fixed pricing? Bonus points if they're Australian.
Honda also offers the 'Shit-Price-Promise'. You can see by the number of dealers they have closed (sorry streamlined) that even if you have an issue with your overpriced econobox you'll need a taxi ride to collect it when it's repaired.
So not only a shit price but an equally crappy ownership experience.
