I believe Mitsubishi is also using Iggy Pop's "Lust for Life" these days, which has some er, um, interesting lyrics (as you probably know from Trainspotting) that they managed to edit down to "I got a ... lust for life." Mitsubishi seems to be the prime violator in this category -- I sorta recall them carefully editing around Elastica's Connection as well.

But Nissan is holding its own by unloading the entire back-catalog of The Who on us (Baba O'Riley, Won't Get Fooled Again, whatever other riff-ish things Pete Townshend and the boys could auction off rights for...).

Then there is Mazda, who used riffs from half of the tracks on Crystal Method's Vegas album (particularly High Roller). Most of that stuff is not exactly typical family fare either.
