I'm a little against suing for honest accidents, but when you're DWI, all bets are off. Like everybody else said: Talk to a lawyer.
The silver lining on this cloud is maybe you get an STi out of it.
I just don't get DWI... My wife and I go out bar hopping all the time, and pay for a cab to drive us. Let's see: $15 for a cab ride, or jail/thousands of dollars/lawsuits if we drive and something happens. That's a hard choice, eh?
