I think this has been posted before but I just installed mine yesterday and wow! do I like this thing. No, I don't work for MG racing and yes I paid for it.

It gets a little hot here in Phoenix and I can tell you that this improves the ability of the car to hold that precious AC in the cockpit. I was nice and cool at 105 degrees today. Road noise is a little less and it adds a very nice finished look to the inside of the top.

I would add this to the list of must haves along with console cover and muz mat.
