First look at a 180 for me is the rivits around the gear box area.
If the plane has been recently cleaned, get someone to push up and pull down on struts hard while you watch the skin/rivit areas under the belly there...
But lose rivits are only a 5-10K repair, depending on what needs replaced there...
Don't be fooled, pay a mechanic you trust a bunch of money to travel to the plane for the pre-buy if you have to. I agree with mtv on an annual inspection type.
If the owner does not want to furnish good pictures as requested, walk away!!!
I like 56-59 years. Pre 56 the gear is a bit farther back, they feel like a high powered 170 which is great, but the structure is stronger from 56 on. After 59, as said, they got heavier on control and weight.
If you are flying big loads all the time, get the big tail one, and put the gross kit mod. But it is like flying a truck, (which it is), not the sports car the early ones were.
I would be happy to do a walk around on planes here. Give me a call...
Justin, like dealing with guides? :lol:
