so i'm new to the jeep family, currently am ordering a sahara 4dr, any thoughts on pros vs cons of the leather seat package, i have leather in my convertible, and love it, but its hot in the summer time, but its also black, does anybody have the saddle leather? also, snowy canadian driving in winter, does the bridgestones that come standard (18") cover me or are they strictly a summer tire or a compromise for both? any help?
