997 S Cabrio, really don't need the extra power, but most cars were ordered that way. Cruising along with the top down, whether on a cool fall night with the heated seats on, or just driving along with the sun out listening to tunes. How can you beat it. There have been issues with some Porsche's but I have not seen it yet. The cable from the alternator to the battery is undersized and can be replaced, but if you trickle charge the battery there is no starting issues. Oh the only thing bas is the early 997 keys.
