I've read a ton of board posts here in PP and other forums, but haven't found solid answers.

My situation: I'm the second owner of a 2002 C4 Tiptronic which is running perfectly fine and is in great shape. That said, it's about to hit 60K miles and I'm seriously wondering about getting the IMS replaced.

Questions:
What have other owners -on this board- of C4's have done; replace or roll the dice?
What is the average cost of getting the IMS replaced through a reputable shop? C4's being AWD, and mine being a tiptronic on top of that.
What reputable shops are recommended around the San Francisco South Bay area? (I'm in San Jose)
What other services can be done at the same time?
Or, how can I tell if the engine was replaced at some point because of the recall?
