What is the amp and cold cranking amp for the battery this car? on 1990 BMW 325i

I ask this question, because all four of my local BMW dealerships parts places gave me different information. Some say it is 65 amps/540 cold cranking amps. Others say 70/540, 50/450, 50/265. But I need to know so I get the right battery.

i'm not sure why your getting so many different answers, but the correct battery is a group 91 w/ 600 cold cranking amps.
