I also flew MH367 from Tauranga in 2012. Staggeringly expensive, although about half price compared to the UK. However, worth every penny, particularly for people's reactions when I casually mention that I've flown one.
A very-experienced flying instructor flew it after I did and he summed it up, in typical Kiwi fashion:
Sitting in the back seat, it felt just like some rubbishy old Harvard, but then you look out at that wing and you know you are flying something special!
This is a still from a video. I'll get my act together and post it.
Handling was somewhat disappointing - super sensitive in pitch, but very heavy ailerons - you would need two hands at high speed.
As SSD noted, the sound inside was all mechanical, but then you've got a lot of moving parts up front!
A highlight of the trip was the rejoin:
Tower: "ABC, opposite direction traffic, a Spitfire, 1500'"
ABC: "Tally ho the Spitfire!"
