Regarding the cost of replacement electronics, I did not have to buy them individually - I had a couple parts cars that most of the parts came from. At the time, I could buy collision damaged 986s for under $3,000. I'll discuss further in the thread you posted about the car.

Thank you for the link to your amazing restoration of your Spyder Anniversary Boxster! I am impressed and grateful for the encouragement it all gave me. If it is not asking too much, what was the rough cost of replacing all the electronics in the car's cabin?
