it's not just FR, our Thor Palazzo has the same issue - it was the manufacturer of the vinyl fabric, claiming that it was 'just as good' as leather, or close to it.
Thor has told me that they were getting with the manufacturer to give me an option, but after months of reminding them, they have still not replied.
