I'm struggling with this right now too. Mines a nice weather only car, which is only may-october around here. The summer is pretty mild for the most part, and I only use AC in my car if its 95+ degrees and I am going somewhere that i dont want to sweat.
90% of the time I drive it is in the evening or a weekend afternoon.
I like mentioned would love the extra space, but it def does hurt resale though. I guess it couldnt be THAT hard to put it back on.
For you guys that did get rid of it, what did you do with the line that goes into the firewall? Did you just hack it off, or is there some other way to do it right so everything comes off with no hacking?
