Advice on buying a 152?

I'm considering buying a 1978 Cessna 152 that the owner is leasing to a
flying club. I'd continue to lease it to the club and learn to fly in
it. (I have 3 1/2 hours now.) I'd hope that plane to earn enough money
to cover most of its maintenance and insurance, including a new engine
in a few years.

I met with the owner of the club this afternoon and we went over some
numbers. The plane and the club's other 152 have done a good job of
earning their keep so far. I could accept not quite breaking even.

I understand that renting is cheaper but I'm really excited about the
idea of owning a plane. I also really like that particular model. I flew
one on my last lesson and it was a lot of fun.

Asking price is $28,000. The engine has about 600 hours since the last
overhaul.

I'd also appreciate any comments or advice.

Thanks!
