I was just looking through a back issue of Excellence magazine, Feb 2003.
The prices of the parts advertised caught my eye... they seemed pretty reasonable by comparison to current pricing.
I don't think the particular retailer is important, I did some research tonight and found that they all had virtually the same increase in pricing.
Here's a snapshot. Note that I compared similar manufacturing, german vs german, not german vs say a newer repro, and brand to brand (hella to hella) etc.
Prices are from the SAME retailer, 2003 and 2011.
Inflation has gone up 23.41% between Feb 2003 and May 2011, from one calculator I grabbed online.
I also know that certain items like say mens apparel hasn't gone up almost at all between this time period...I was in the industry for almost 30 years, 2003 pricing was virtually identical for a like product between then and now, but production probably did move from one country to another in order to keep the pricing.

A possible causal of combining exchange rate impact "and" inflation might cause the above pricing increases, but I would also think that the manufacturer would move some production to mitigate these factors to some extent. Unless of course the people who price these products think that Porsche parts buyers have inelastic demand. Which to a great extent they might be right, particularly as there probably wouldn't be very many manufacturers of a particular product.. it probably is just one.
Please note that these particular prices are pretty good... particular as I just ran them against Pelican which was MUCH higher than the 2011 prices of the retailer I used for them above example.
cheers, should be an interesting discussion.
