I put an Optima redtop in my Lincoln LS about the same time I put a roll cage in it. A month later, on the starting line at an ECTA meet, the car died. We diagnosed a faulty alternator and replaced it by flashlight in the pits that night after a quick trip to town. The battery never was any good after that---wouldn't hold a charge. I emailed Optima and tried to ask some questions and couldn't even get the courtesy of a return message. As an old friend once said, "Scroom". I'm done. The best deal around seems to be the 'biggest & best' Costco has to offer. As I remember, about $85.00.
