As a matter of fact I do, since I have personally taken apart my porsches--checkout my website for verification
http://zoomzoomvroom.com. I have also owned a few vettes or done work on them as well although I have not personally worked on the C6 a friend of mine had one apart last week so the interior is one area where the quality is better although that is merely an example inside my overall statement. -by the way I like the vette.
Oh yeah, I was involved with GM motorcar division specifically cheverolet and specifically corvette in the mid 90's in regard to the electronic rights to the history of the car and was granted access to all aspects of manufacturing and design. For example to bore and hone a cylinder for chevrolet for the corvette takes less than 1 second, honda takes 8 and porsche takes a similar amount of time. What this means is that they can pump out more engines, but the quality is of the operation is less. Also observable is gap in quality between parts which, if you have seen both cars up close as I have is obvious. Paint,the process and amount used is less for the corvette as well.
In regard to my statements about engines, Porsche engines, at least in the aircooled variety are very similar to aircraft engines, something I am also quite familiar with as I mispent my youth restoring WWII fighter planes as well as more modern fare. These engines are designed to perform optimally in cruise mode at a given set of RPM, fuel enrichment etc.. as is the porsche. It is designed to be able to perform best for a given set of circumstances high speed and handling. That being the case based on my experience I have found that like the airplanes I worked on my porsches everything from my 67-to my 996's and boxster S get vastly better mileage 14 city 24 mpg at 85 miles per hour than my vettes whose gas mileage goes into the toilet in the same speed range. (12) C5.
Let me say I love vettes, I also see and understand that building that car for GM especially when the C5 was being developed had to be built to a price point and therefore where one could get away with things in the corporate parts bin one would. The advantage of this is that GM is able to do certain things with the car as they are building a larger number of them. However, having said that I would expect better quality for the price. I believe current vette production is roughly 32,000 units or more while 996 production is, roughly 15,000. Furthermore if you did a bit more homework you would know that Chevy uses a completely different block for racing the C5R. Porsche uses the GT3 engine as a basis which uses the old 964 block, however I believe that they have worked out the problems with the M96 (one can hope) and it will be now used in the GT3 as well as the rest of the line.
Having said all of this I am acutely aware that some of the parts of the porsche do not thrill me to death either these days, however my general observation is that what we get today in general shows there is a lot of inflation in the world economy, it reminds me of the incredible shrinking candy bar for the same price.
So my advise is go take the cars apart as I and my friends have done recently and then let me know your opinion.
