The Porsche Turbos are not cheap cars, my father has well optioned '09 Cab (pccb, deviated stitching, etc) and the MSRP was in the 160s.
The 2010s are supposedly even more,and I'm sure the Turbo S is even more than that. I bet a well optioned Cabriolet can approach 200k in the Turbo S form.
I mean for what you get its a great machine, but its about progression.
A 458 italia will be will into the 200s, the DBS is 250ish, the convertible is 300.
Expensive? Yes, but priced appropriately.
