Thanks Matt. I've found a website with the actual rates and the formula, so have a rough estimate of what it should be for each car already figured up. The biggest variable of course will be what they value the car at, vs the Kelly Blue Book values that I used, as well as length of ownership (one of my cars is a 2006, but I bought it in mid-2007 as a leftover) I'll assume worst case so that there shouldn't be too much "sticker shock" at the DMV! I should know if it's even going to happen this year by the end of next week, if not, I'm putting of searching further until late this spring when I'm almost out from under my current relocation contract (the big fly in the ointment in my last interview i think, which otherwise would have been a done-deal)
