I have owned my 99 for 17 years and sad to say I only have 33,677 miles on it. I have had it in storage for the last four years and just decided it is time to get it out. I just changed the oil & filter along with doing a drain & fill on the radiator. My tires only have 5,000 miles on them. Belts, hoses and K & N look good. I'm thinking about changing out my rear differential fluid however it was done 5,000 miles ago along with the brake fluid.I forgot to punch out the date on my red top battery so I don't know how many years it's been in the car, probably about 8. As mentioned my car has been in storage the last 4 years and was only driven 1,000 miles the year before that. Always garaged and always on a battery maintainer. Any suggestions before I start driving it ? I must confess the car hasn't been getting driven because of riding my motorcycle. With all of the texting drivers my safety concerns have been growing therefore I have a renewed interest in my Corvette. Thanks for your comments.
