i decided not to get Optima....heard they weren't really made for civics.....it was $149.99 at Autozone..with 1 year warranty 625 cranking amp and 500 cold...same exact specs as the DUralast i got for $75. with a 3 year warranty..i needed something so why not...save some money..and hopefully it'll last longer than 3...didn't have much time to research optima..
