I’m confused…

I’m looking to buy a new car, so I thought I would do a bit of online research. I went onto the Toyota website, which is quite a good site overall. However I was looking at customising a car and clicked on the options tab, where I was presented with what looked like it should have been a list of options, but instead there was one item ‘no options’ with a checkbox next to it. I really don’t get it. Why should I select no options? By not selecting anything then that is no options, isn’t it? Furthermore, why is there no other options to select in an options box?
