Just last week, I left all the lights
on on my '01 E-320 sitting in the garage. Came out 5 hour later to the sound of nothing. I couldn't get my Vette out of the garage to jump the wagon, it's a two car deep garage, so I called the MBRSA and they called my dealer, four miles away. Within 30 min. tech showed, jumped the car, reset everything, we bantered a little about my Vette, real nice tech. Thanked him and all was OK! What else can I say...it works!
