I dont know what I was thinking. I just bought another 69 Firebird. What is wrong with me?

This one's a 400/4-speed and it has either a 3.31 or a 3.55 posi. silver with black deluxe interior and front disk brakes. It has a WZ code engine with 62 heads. I got lazy/stupid and did not check to see if it's matching number, because I got wrapped up in the moment. But I'm pretty sure it's a 400 car because it has guages instead of idiot lights, simulated wood grain dash, console, nice steering wheel. The engine is tight, clutch does not slip, transmission shifts like butter. Posi works too. Feels really smooth and tight.
