Lost 90’s rap

I’ve been looking for a 90’s song for a while. Not much information is known about the song. I know it’s from the early 90’s and the chorus is along the lines of
“She’s a lady in a Mercedes heartbreak on wheels.” it becomes duct after that but I remember “the illiest of the illy when it comes to ills.”
Around Ten years ago a yahoo user posted for help finding the songs. In this post, he stated the rap sampled whitehorse, but he/she very well may be incorrect. Hopefully this song can be found and prove i’m not crazy
