Hi, my name is AJ, I am from Phoenix Arizona, I bought my C5 new about 20 years ago when I was living in Montreal, Canada, it has the double battery set up, which was already installed. I used it for 2-3 years and stored it in my dad's basement when I moved to the USA.
I finally, after 17 years of storage, got it back last week, cleaned it, changed the tires, put a battery in and... WOW it works like new. After making a search on Google I found this forum and I am glad I am glad to see that you guys still love your C5.
