Yeah, I see that.
But if you try one of those additional colors it will force a configuration change and you'll need to pick a trim model that corresponds with that color. I was referring to the SR5 trims only having the 3 color in Canada. Give it a Try
I must be losing it. I'm only seeing 3 exterior (White, Underground and Black) colors for the SR5 on the Canadian site. Where Toyota.com I'm seeing 6 colors for the SR5 trim.
