Why is 4S 20K cheaper than the Turbo?

[kimwex]

another way to ask is what does the Turbo add to the 4S that's worth 20K? The extra 100hp? Anything else?

Here are some additional gains with the turbo(4s option cost):

-Larger front brakes by 1” but still 6 piston
-metallic “shade” colors no cost ($690)
-21” turbo wheels no cost ($2710)
-wheel cap logo consistency ($190)
-Leather package in black ($960)
-18 way seats ($1720)
-standard black window trim ($240)
-ext mirror color no cost ($600)
-side blade color no cost ($680)
-front valence gloss black no cost
-rear bumper lip color no cost
-ptv ($1490)
-matrix design lights ($1220)
-rear Porsche logo black ($290)
-interior accent color ($540)
-sport steering wheel ($320)
-race tex roof liner ($1540)
-Bose ($990)

The value proposition is debatable since many of the “upgrades” are detail color specifics purely asthetic. Depending on how lightly you spec the 4s vs how closely you spec the 4s with standard turbo options will result in approx 10-15k price difference.
