COSTCO has OPTIMA 75/35 Red Tops model 12853 at $115.99 and a $25.00 rebate. I put one of these in my old '02 MCS and it worked and fitted just fine. This one's going into the '06 this afternoon.
Fit looks decent, but price wasn't that great. I picked up an Exide Orbital Extreme for ~$80.00 a couple years back for one of my other cars.. that was a pretty decent deal!
I've had at least 5 different Optimas - can't complain, and their warranty is decent. I just re-read the OP's post and realized that it would be under 100 total. I must have read it wrong to begin with because I thought it was like 120 bucks stilll HA HA HA
I'm not a fan of these batteries, when I owned a 3rd gen. Acura Integra, I had both red & yellow tops go bad within a short amount of time. when I addressed this Optima they would not warrantee it due to the fact they were no longer going to make the size for Civics & Integras. They might have worked out the issues with them by now but I'd rather use an Interstate.
With a 3 year replacement warranty and 90 bucks out of pocket, it works for me. But I think either the price or the rebate opportunity expires on 8/31.
Oddly enough I thought I had a problem with my red-top optima at first - but it "fixed itself" and it's been fine for over 2 years now... {shrug}
