I think a good strategy would be to offer more options as Dealer Accessory Upgrades and not factory options. That way, some people could be as barebones as they want and others could get whatever accessories they would like; And even if people couldn't afford the options at time of purchase, they would have an ability to purchase the accessories and have them installed after the sale. Sadly, Mazda has relied on the non-OEM approach and is letting third parties make any accessories for North America (so far).
While I wasnt able to afford it at first, I would pay $1000 for a factory set of HIDs or a Good Stock Nav Unit (both of which are made, but would need to be slightly adjusted for North America). Heck, I'd likely be willing to put out $3k for a "Mazdaspeed Upgrade package", even if it was just tuned suspension, brakes, exhaust and a 25hp upgrade!
As long as there are options people will be happy. And like you said. You can buy it or not. Your choice. And i would love a Mazdaspeed Upgrade package.
