Do you use your A/C
I also love to have windows open, but...
At any speed over 40, the wind is a bit much and my hair becomes tangled and unruly, plus...
In FL we have 98 plus degrees and 98 plus humidity percentages for the better part of the year.
It's a big plus to have working AC in a 45 year old car.
I'm 51 and the last classic I had with working AC was my 73 Duster in the 90's.
It wasn't great and I didn't run it a lot but was better than not having it, especially in the rain.
Not quite 40*, but we'll call it 47* and be happy to have that on those over 100 degree and 98% humidity days.
