Welcome.
I have an 05 Boxster S too. Love that car. Had it for about 13 years and no desire to move on. I think one reason I’ve never addressed the IMS issue is because the only reason I’ll get rid of the car is when the engine implodes. It’ll give me an excuse to buy something different.
Even though I have a 718CGTS, the Boxster is so different, I enjoy keeping both.
On paper, I have been speccing out an air-cooled 911 hot rod build. I’m out of garage space right now so would need to build a garage first. Also not thrilled about 1) how long it will take me...I’m pretty slow and 2) the mistakes and wrong decisions I will make along the way, only to have to backtrack or pay to do things twice. I think I am more Interested in the final product than the process. Still mulling it over. I’m also not a fan of the financial black hole that I might fall into.
