Just before I bought my 2001 Boxster I did a test drive on a ' 99 996. It drove well but needed tires. He wanted $20k can and it had 100k miles. I ended up buying the Boxster which ended up having engine problems but not ims specifically. In hindsight the 996 would have been a good buy. It was faster than the Boxster but did not feel so sporty.
Your video is an inspiration for the old water cooled 911. Who knows if a 996 would have fared any better through three Canadian winters.

As regards ims failure then it was not unusual to hear about the failures in the forums.
The 986 forum had a poll on engine failures for the Boxsters. I am sure there must be a poll somewhere on a 911 forum.....

I would think the results would have been similar because the engine design was the same even though there was a range of engine sizes.
