I bought a Bosch battery at pep-boys for my 300SD and it was under $100 with 1000 CCA. It fit perfectly in the holder and seems to do fine and the car sprang to life fine the other day when it was well below freezing. Also, the nice big red Bosch label on it seems more appropriate than some of the other aftermarket brands when looking under the hood too, but that is probably not the best reason to choose it.
