OK, same old airframe, but newer seats and covers, newer canopy, newer harnesses, newer controls.
A few Łk of cost, but a much improved customer experience.
These planes look the same as when I was a kid and my dad took me flying 20 years ago and they were not new then either!!
I am convinced there is a middle ground between BIG BUCKS (your phrase) and TIRED LOOKING AIRFRAMES & INTERIORS (my phrase)
