The heated steering wheel makes a difference especially if it’s a wood wheel. You do have to position your hands on the leather but it’s a nice touch. With Lexus there are two types. The ones in the IS-GS price range use a pipe from the A/C into the seat to blow cool air. The LC/LX/LS uses a fan inside the seat that sucks air from under you. There are fans in the seat. It’s much more effective but a bit louder. I lived in Miami for 5 years and it makes a difference.
