[S] Car commercial with song I only know from a parody

There was an ad for a car a couple years back ( I don't remember which year exactly) and I hardly remember anything about it except a lady was putting lobsters into a cooler in the back of her car. The thing that I recall most was this song that brother parodied by singing: "Mummified, sleep in the ocean." I recall the lyrics going something like "summer nights, ____________, 16 driving my new car." It might make the search easier if we could find the original song that he parodied. I've looked for quite a long while for this ad. It'd be great to get some help!
