The Solution makes the most sense for someone that plans on keeping the car long term, like Jake mentioned. If you are going to keep the car for an intermediate time and you need a clutch, get the retrofit. For someone who changes cars on a regular basis, get one, drive it like you stole it, have fun, and move on to the next desire. Regardless, the Boxster is an incredible value with or without the additional cost of the IMS Solution or retrofit.
