2006 Nissan Xterra

I’m selling my Nissan Xterra. I really love the truck, but it drained my pockets to the point where I have to let it go. The engine has seized on me last year. After coming up with a lot of savings,I got an engine for it for 2k, and had it rebuilt. I spent over 6k on the truck. (Documentation, and receipts available)Transmission was replaced, and works fine I went and put in brand new front number ( I had a dent on the previous one) new shock absorbers front and back. I just put in a brand new music player, resurfaced the rotors, new brake pads, battery, uninstalled fog lights, and plenty of other parts on the interior. The car is clean, I’m selling as is: However, It does start now. But my mechanic told me that the engine I put in is misfiring and that I need a catalytic converter. I gave up on spending more on it. Asking 2500 OBO to leave room for it to be worked on, or sold for parts. It’s a win both ways, I just don’t have time to work on it. Pink slip on hand, ready to go!
