Only done 850kms so far but have exceeded 6,000rpms once or twice as Lotus here recommended to me. Haven't linked up three or four corners at max rpm and breaking etc. but do intend to this weekend.
The aircon works fine - particularly with the roof on - just like any other car.
In direct sunlight with the roof off and the aircon going in summer it's just like any other convertible, you get cold air flow where the vents are pointed but are warm everywhere else.
Pretty good all in all.
