This is exactly why Porsche is a horrible value new, but a great value used. You can get some very nicely optioned Porsches for only a little more than their bare bones counterparts on the used market. The cost of those options hold little value in the used market.
I bought my 2009 Cayenne GTS with only 8600 miles on it for $67,000. New It was over $91,000. It came with Porsche Dynamic Chassis Control, a $4000 option, and The Sport Design wheels, which were $3500 upgrade. I paid virtually NOTHING for these upgrades on the used market.
