A friend of mine thought I did well with the AZ battery... I did a google search and came across some cool news... http://www.johnsoncontrols.com/CorpPR/Releases/battery/release786.asp
Check out this link... those great AZ batteries are made by the same company that makes OE BMW, Interstate, and Optima batteries. So you are saving some good $$$ on a top quality battery with a different label!

Thanks again for the advice guys... Happy motoring this winter... BTW... I read that the SDL has a built in block heater? Where do you get a cord/plug for this? I want to take the L boarding this winter and will DEF plug it in!
