Most Overpriced Part?

How about Porsche special tooling:

RMS tool at $650

Thermostat extraction tool at $125 (you can buy the same tool from LN for $15 or make your own for about $1).

Vacuum cooling system filling tool at $850, or buy it from Amazon for $115 without the Porsche logo.

PIWIS at $20K lease for the first year, and it doesn't even include everything the dealer version does.

I was shocked by the coolant expansion tank cost...and the labor involved in getting it in. I think it was about $800 at the Indy all said and done (I had no time to tackle it, jury's out on the skills).

Most cars that's a sub-50 buck trip to the auto parts store and 10 minutes in your garage!

Have to agree with the center wheel cap removal tool.

However, I would like to suggest the Hardtop Install Kit for Honorable Mention. It consists of two little inserts and two small hardened flat head allen screws. It can be had from Suncoast for $95.00. If you get the Porsche Approved kit/version, (I believe it includes a ball end t-handled allen wrench) it is just shy of $200.00 plus shipping.
