Without knowing what it is, it's hard to say. But I've reg'd names with only 50 Ovt w/o that have gone on to make $20+ in ppc over a year, and names with Ovt w/o in the tens of thousands, that aren't worth renewing when the time comes.
It's not an exact science - check what the bid prices are for those keywords, if they are worth $1+ a click you've got a better chance of it being profitable than if they only get $0.05.
Finally, make sure the names keywords are in the right order - Ovt sometimes lists them the wrong way round, ie 'insurance car'.
