First off....Congrats MTS, I'm very happy for you on the outcome. It's also reassuring to know Porsche of the Village is a standup outfit, especially since they are close by for me. Lastly, I did the IMS Retrofit in my garage without a lift and had no prior experience working on Porsches. It really was not THAT big of a deal, it just required a little research, $150 or so in hardware (jack stands, trans adapter for jack, sockets), Bentley manual and patience. I probably had ten man hours into the job and could likely shave 2 or 3 off of that if I had to do it again.
