I remember seeing it on youtube.
It starts with a blond girl being gifted with a blue I think chevie convertible from her parents. Then it goes on to her driving it dating in it, getting kinky in it and being proposed. Then driving away married, rushing to hospital to give birth then goes through the stages of a baby, rearing the car twice and paying for the cars repairs. Then it ends with the same car being gifted to the girls I suppose daughter.
