Could the 2006 Boxster S be the best 987

I may be biased having this car but after reading many articles on power, reliability,
performance ect from Hartech,it would seem that the 2006s with the 3.2 Liter engine is holding up better.The newer 3.4 in the Boxster/Caymen in 2007 thru 2009 are showing signs of Bore scoring.Apparently as per Hartech the 3.4 and up motors are pushing the limits of this design with heat and cooling plus other reasons like the piston coating that Porsche was applying up to and including 2006 was scraped in favour of a cheaper less durable and more environmentally friendly coating that with the extra heat created with bigger pistons/cylinders in the same case but with smaller (more restrictive) cooling ports (same case just less meat on it) the Locasil cylinders coating isn't holding up.
Also worth noting is the 2006 had the newer version of the IMS which seems to be holding up very well as this car is now 11 years old and its lots out there I have yet to read about any failures.The 2005 still had the older design and was susceptible to IMS failure and therefore part of the Porsche lawsuit.I believe that down the road the 2006 Boxster s with the newer design body and interior with the 3.2 ,special coated pistons ,Larger IMS bearing etc will be looked at as one of the better years to own for reliability,performance and price.I think that Porsche had extracted the maximum HP or performance out of 3.2 while retaining the slim margin of reliability.Its a fine line between cost/performance and reliability and I believe (Based on Hartech article) that Porsche pushed the envelope with the 3.4 and up just past the safe limits with all the small changes over the years to keep increasing HP and torque .The older Boxster never showed problems with Bore scoring but they were smaller engines putting out less hp and torque.Keep squeezing something to the max without spending more money on testing for long term reliability and eventually somethings gotta give, the weak link will surface. I am sure there are cars that will not have issues and some that will that shouldn't but this is my long term vision on when looking back what may be be regarded to as the year to get.Ok let me have it!
