Congratulations Dennis!
I'm also getting my private and logged my first hour last weekend. I flew with my dad growing up, until he got out of flying in '05, but now that I can get my license, he decided to get back into flying, and we also bought a 150/152 instead of renting.
You're going to make a great purchase i think, just for the sake of owning a plane, looks like a fun project to bring back to its former glory too. When we bought ours, it'd been sitting over a year from the owner losing his medical, but it was in good condition mechanically, recent paint, but dirty. After a fresh annual and good cleaning,I've flown in it with my dad about 9 hours in the first month of ownership, and we've just had the attitude and turn and bank rebuilt so far.
It's been great just going out flying in the late afternoons or weekend to little airports or anywhere, and meeting other pilots while just tinkering around in the hangar by the plane. Those kind of experiences from owning a plane makes flying even more fun i think, and hopefully buying your "new" 150 will be a great experience too
