Check the Autostyle mats with Trophy embroidered and the car number about halfway down the thread. Too large a photo but you can see what you need to see with a bit of scrolling.
I went for the footplate to stop them wearing out too. They look OEM and are spot on IMO. Black with grey or silver piping, go for the 'luxury' ones. Worth every penny. They are perfectly fitted to the footwells and don't slide around either. They are almost so good you'll want to keep them clean like they are the carpet! I got a full set, including rears, they fit perfectly as well. £70 inc VAT.
