Think "FRED" might already be taken. In some quarters it is actually an acronym that stands for "F**k**g Ridiculous Electronic Device" and gets generically applied to computers and other related binary items that have tendency to glitch or crash at the most inopportune moments. Guy I knew developed the term in response to the girls in our office complaining bitterly about the branch main frame. I thought about it and decided that the girls got to call computers "Fred", then for guys it should be "FREDERICA". Hey, EEO.
To me you just don't name a car after a guy. And my wife keeps calling it the Flintstones' car.
Although to play of your version of FRED, "F**k**g Rusty something something" could work too.
