I have heated seat mats in my Roadster. I am dead set against "upgrades" to Morgans such as power steering and suspension "improvements" as these things take away from the traditional character and feel of the car. But heated seats are fine - just a way to keep a bit warmer in the dead of winter when the hood is down. Mine get hot very quickly though - and I can't have them on for more than about 10 minutes before my posterior starts to feel scorched.
