buying GA plane

[luqman_hussain]

just like to know what is considered, in terms of hours/flight cycles, a:

rather new plane?
moderate age plane?
old plane?

for general aviation. i only know about the mileage on cars, not very sure about planes.

also is it considered better to buy an old plane (say 1960s model) with 5000 flight cycles or a new plane (say 2003) with 10,000 flight cycles?

thanks.
