Local rate is about $200/hr wet for a C-182RG. If your dry rate is $80 and fuel is $70 that's $150/hr. That leaves a balance of $50/hr to pay that $500 annual fee. Fly more than 10 hrs per year and you are saving $$. Now how hard was that to figure out. Purchase price and associated cost to operate a Cessna 182 will be dependent on the year manufactured, total time on the airframe.
