Spark Plug Change Help - Stripped Torx Bolt

I began removing the torx bolts holding the coils on my 1999 Mercedes e320 and got all but one free-the front most one on the drivers side is stuck and stripped. There is not much room to work with in there to try any of the suggestions I've seen on other sites to try and get a torx bolt out.

Does anyone familiar with that car and those close quarters have any ideas on how to get that bolt free?
