Looks good except that battery in the trunk, that sucker has GOT to be vented, or you're going to inhale a lot of fumes you don't want to, and everything in the car will corrode at a pretty quick rate. It's going to offgas, just by the nature of the battery, if anything, at least put the Optima in the back. At least it's a sealed cell battery and no risk of turning the car into a roman candle.
