Stay away from lease backs!
My 7KCAB was on lease back at an FBO where the owner had a chief, the mechanic had a stearman. Even so, they managed to drop something on the wing while it was hangared, and 5 months later it is almost finished.
Without those repair costs, I have to say it is a durable bird. It is also easy to do owner maintenance, and many A&P's are willing to supervise on this kind of bird. This makes it a much more enjoyable experience....feel like you are part of the plane. It is also much cheaper for maintenance and repairs.
If I fly only 100 hours per year, my cost of ownership is around $48 per hour. It drops dramatically after that. Insurance was $950 (I only have 50 hours in type and TW), hangar is $150 per month.
Best of all, is the ownership experience. No one will walk up to you at a grass strip and say "hey nice 172", everywhere I go, people want to talk about the citabria, and many of them have a cool plane of their own to show you.
One other thing, do not get sucked into the anti-wood spar conspiracy. Of course get it inspected before you buy, by someone who knows, but I can tell you that a complete rebuild with wood spars, poly fiber, and a fancy paint job cost $5000 less than the new metal wings and weigh alot less too. Other than the hangar rash my original spars were good after 30 years of acro training.
Buy it, Fly it, Enjoy it!
