So I've been having some issues starting the 2007 Coupe. It hasn't been driven much this year, basically sitting in the driveway under cover. On the cold days we had last week, car wouldn't even crank. So today i removed the Super Start Extreme 48 H6 battery I bought from O'Reilly's 3+ years ago, and went up to the local Walmart to get an Everstart battery. Ended up buying the Platinum AGM H6 version, with a 4-yr replacement warranty. Never been a believer that the AGM battery design was worth the extra money over the Everstart MAXX H6 3-yr replacement. But Walmart was running a sale on the Platinum AGM version and I bought it for essentially the same price as the 3-yr version. (Note: All these Everstart batteries are still under $200 versus the other battery sources.) Anyway, Coupe is back to starting like it should - time to take a weekend trip with it when weather warms up..
