Okay, husband's opinion is that Marge/Margareta is a good name for a Mercury, "Margareta the Mercury Grand Marquise".
In the end it's my car, but I know he's going to put a stink up about it.

Which is fine, because if he likes it too, he'll call her by it, which is entertaining to me.
He didn't favor my suggestion of Loraine, too old of a name. He briefly suggested Loretta but still was not convinced.
His suggestion, something that sounds good with an L, a T, or a C, and not French because she's not a Cadillac.
