Isn't it just like anything else to do with this hobby? If you want the Wilton, just do it and don't worry about what anybody else advises. And it's true, the only person who will know what sort of carpet it is is you. Probably, every time you sit in the car, it won't particularly worry you that you opted for the
synthetic, but if it's a Wilton you've got, you can sit there smugly for a couple of secs before firing up
Go Wilton!
