I bought mine when I was a student pilot with 25 hrs. I couldn't go get mine and I didn't fly to NJ to see it 1st. The owner owned it less than 2 yrs but bought it from his buddy who owned it for a few decades. I talked to the previous owner for a few hrs before I had the owner deliver it to NC. I believe I paid about $5000 deposit (by personal check, I thought I could trust him, I was right) a few weeks before it was delivered. I had a bank check for the balance ready for the owner upon delivery. We sat down in my fbo and did the paper work. We tied it down then I drove him to RDU to catch his flight home. The owner was a sheriff, I thought I could trust him (I was right). The previous owner was a business man, I thought I could trust him (I was right). Everything they told me about the plane was correct. I've owned it for over 2 yrs and have not found any surprises.
I saw lots of pictures, all logs, talked to the a&p who had been maintaining it, researched the owner and previous owner...but I didn't get a pre-buy. Turns out it would have been a waste of time and money. I would never recommend anyone not get a pre-buy. I believe mine was a unique situation in that I was able to talk to all the different people with knowledge of the plane. No regrets.
