That conventional panel has all the capabilites of the G1000, except the onboard W/X map & satellite radio.
As for if the new $172k Cessna (thats the base price, not $million/4) is worth the price, that is up to the consumer & plenty seem to think they are.
Maybe its that new plane smell?
I'd guess you'd spend about that buying a used one & upgrading it to an equal quality of plane.
I've flown two Penn-Yaned 180HP 172s & neither had the cruise performance of the SPs I've driven (of course one was tricked out with a bunch of STOL equiptment & the other had a very rough paint job).
The last SP I flew did over 130 TAS at 2400RPM, 6500' about 10C over standard temp for about 8gal/hr, 50 rich of peak.
IMO 180HP is 180HP & whoever has the slicker airframe is faster (or the Skyhawk XP guy who comes along & pwns u)
