W152 6.0 V12 Rebuild, 2016-21
The original exhaust system gave up, and really needed an increase in diameter and depth of tone. I had been hankering after a 6.0 with modern engine management, so the project grew into a complete "back-to-chassis" renovation - planned for completion Spring 2017 (revised to 2021. This was because of a brain abscess, followed by a leg arterial bypass, followed by a house extension project which blocked all the cars in the garage, followed by cancerous brain tumour and the CovID-19 lockdown). All this has led to closure of the business and sale of this magnificent car.
These slides show some stages of the project -
