Spitfire... pah.

Mig 29 for the win.

I did this a few years ago. Same aircraft, same pilot as well. Got to 72,000 ft and max speed of touching 1400 mph.
Paid extra for the low level aerobatics at the end and can't remember a thing about it other than trying very hard not ...... to...... black.... outttttttttttttttttt zzzzzzzzzzzzz

Cheaper than building a kit car as well.
