How do I prevent ENGINE HEAT from coming into the car?

[TheBreeze]

Hey Ya'll, This is my first post, and I am thinking about buying a '31 Model A Street Rod. I have never owned a STreet Rod, but did have a 1928 Studebaker Touring Car. The HEAT from the engine was so hot, that you would sweat in the wintertime!!! I sold it about 15 years ago, and have not been back in the 'swing' of classic cars in a while, so any advice on how to prevent the engine heat from running me out of the car would be appreciated. Oh, also, I've looked at some other rods for sale. Most do not have heat or AC; how hard/easy/expensive is it to have that installed? Thanks so much, and I look forward to hearing from you. TheBreeze
