You might well be the only customer that wants red floor mats in your IS300h, in which case it would never be worth Lexus offering them as an OEM option. Even if you aren't the only one, I doubt there'd be enough customers to make it worthwhile. I'd quite like to see an IS450h as a halo model but doubt that will happen either. Buying the fabric patches and sticking/sewing them on sounds like a good option if you really want red floor mats. Let us know what you do. Pics too please
