i dunno... gm sucks

I'm on the phone with Mercedes Road Side assistance to see if they can get out here and get me started and then run out to orlando to pick up a voltage regulator

and since the battery is dead.. a jump box will not be of help... I just need to get it started so I can drag it to my mechanic out in Orlando and get a Voltage Regulator swapped in.. He is a lot cheaper than the dealership for parts..
