Has anyone added a heated wheel on one of these 9th gen cars? I'm looking at a bunch of low mile ex rental Premiers and it must be rental spec to not get a heated wheel as none of them have it. Odd considering all the LT rentals do but don't have Bose and whatnot. I'm thinking it would be like in my 2017 Sierra where all I need is the steering wheel, clockspring and maybe a power harness if it's not already there. Just curious!
