What's the name of the book where a girl goes to stay with her two eccentric aunts over the summer?

I think she falls in love with the guy who is repairing her aunts' house. And I think it was published in the 80's. I don't remember much about it, but the title is driving me crazy. I think at one point she has to drive her aunts' car and its a hearse. Any help would be appreicated.
