I suppose that if I agree with you, on the 6, you will go buy a turbo.
Seriously, the 6's are usually option limited, smaller brakes, no PASM, no full leather, interior trim plain-Jane, minimal seat memory (if any) lumbar support, parking sensors, auto-close rear hatch, power adjust wheel, auto-on lights... the list is huge.
The PASM is a big deal IMO. Mine has it, my wife's does not. The PASM allows damper adjustments, as well as ride height adjustments. It also means you have an air compressor onboard, allowing for a 911-style space-saver spare tire. (not one of those puny ones).
The Bose sound system is the best OE system they made (according to a guy I know who helped develop it)
So, I'm saying, find yourself a nice turbo.
or am I?
