Fantastic present, be sure to take some pics/video if you have a camera and the pilot will allow it - then you can share your great gift with everyone later (ie, us).
I took a similar ride in a Harvard years ago, very similar aircraft, the Canadian/British variant pretty much. Louder than I had expected, but smoother as well - the gentleman who owned that plane and used to sell rides in the yellow pages in Calgary unfortunately passed on, but 15 years ago it was a fantastic value for the $.
