After 11 years 09/17/03 and 8116 miles my battery finally gave up the fight on my 2004 coupe. Always been on a trickle charger when in the garage all these years. I was surprised it lasted this long in the weather we get in Omaha, NE.. Still have original wiper blades and never tried them yet. Went ahead and changed oil and air filters K&M. Should be set for a couple more years. Can't wait for Spring to go cruising.
