I have leatherette seats in my 325i and loved them until summer. For some odd reason the driver’s seat (sport bucket) is noticeably warmer than the passenger. I do live where it’s hot (80-90); however it’s so uncomfortable that I drive my other car during the summer months. Has anyone else had this problem? If so, what did you do? I’d rather not get seat covers but I think that may be my only option. Even then I’m not sure what kind of material I should get and the BMW service center I called wasn’t much help.
