From TUAW here there is news of a 1969 Pontiac GTO a clever guy has remote controlled with an iPod Touch.
I never managed to get my GTO controlled by an iPod. Wait, mine was the 1968 model. I should have waited a year. Of course mine did have 8-track. The motto is,"always wait a year before buying, unless you want 8-track." (I forget, does the first model iPad come with 8-track?)
