In any case, I think anyone with a battery problem might as well save themselves some grief (alone on a trail with a dead battery??? ) and get an Optima. No, I don't make them, sell them or own stock..wish I did!

I went through two GM batteries on my 01 Vette before I gave up and bought an Optima. A little expensive, but I know it won't leak, damage a computer or leave me stranded.

Only problems Vettes had with leaking batteries was the side post batteries. In 2002 they switchd to AGM batteries that can't leak, and in 2004 they went to a top post. I would not worry about a top post battery leaking.
(I will say that whoever designed the computer below a side post battery should be sent back to school.)
As for GM batteries, well, GM does not make batteries. In addition, as I have stated before, batteries are a problem for all manufacturers, battery failure is extremely high at any vehicle manufacturer, especially if the vehicle is in a very warm location.
Optimas are great, might be the best, but they can also fail, but their failure rate is a hell of a lot lower than a normal wet battery. (I had one fail!)
To be honest, the last battery I replaced was my Jeep. My vette batteries never gave out, my H3 battery is still going strong. But in all honesty, if I do have a battery fail, I will install a red top, unless I install a winch or other high amp device.
