I had 'heated seats' fitted by Allon White last year at £70 less than the MMC price quoted. Best after market extra I have ever fitted. They are basically mats of wires that sit under the leather and on top of the foam cushion on the seat and lumbar region of seat back. After sitting on seat for a long drive you can just see the outline of the mat. Went out last w/end and had them on full (2 settings) and got home warm as toast
