Hi, If the plastic ring on the mat has a small round circle in the middle - just pull them upwards hard. If you have the twisty fixings (which you probably wont) then you, er twist the fixing.
New mats with the nipple :embarassed: fixing are quite tight. The worse thing that could happen is the plastic fixings come apart from the mat, but they just clip back in anyway.
Nice car BTW, good choice!
