I called MB roadside service this morning at 6am. Local dealer called back within 10 min. . I guess service manager or senior mechanic gets called at home if shop is not open for business , yet. Two options...will jump start for free and I can drive to dealship and have new battery installed...or can install at my house..but will be charged time and a half. I opted to have the car " jumped" and I drive it to dealership.....about 2 miles away. Dealer rep arrived just after 8 am. Dealer checked condition of battery at dealership..failed test and replaced original battery with a Silver Calcium B . Cost of battery..$153.60 plus tax $12.67.....plus Labor $76.50....Grand Total....$242.77. All controls reset...radio, sunroof, seats , headrest etc. and washed car and cleaned interior. I guess I got a very expensive car wash and clean interior for $ 76.50
