Alexander,
Go luck in looking for an airplane, But if I mite make a suggestion, don't buy a plane until after you solo and have a few hours solo. Why ? I have seen a lot of people take flying lessions , solo and then stop flying and never return.
One of the reasons of buying for me is saving on rental. My wife and one of my friends are going to the same school. By the time we all go to solo, we would spend (combined) about 10K for rentals only.
Buying and sharing expenses sounds like a better choice to me. Is there a catch that I do not see?
