Plasmech, you lucky, lucky person.
I fly a 152 at a not-for-profit club and it costs about GBP 100 an hour i.e. about half as much again as you are paying. At a school that has to make a profit, it's about another 20%. At least in the US the instructors seem to be properly paid. Here something like GBP 15 (USD 25?) seems common.
Avgas here is I think (it's included in the club rate so I don't know accuratly) about GBP 6 (about USD 10) for a US gallon!
