Shouldn't have left NY, too much crime down south, who am I kinding its cold as hell here, wish I was there. Congrats on getting your car back. Go to Walmart pick up a cheap battery, bring a few wrenches with you to losen the battery terminals, dont worry about the exhaust, drive it back to your house, if you get pulled over just tell the cop what happened, he'll understand. I wouldnt suggest bringing it to the dealer, if you're going to sell it I would bring it to a regular mechanic and tell him to fix what needs to be done in order for you to sell it.
