That's a great deal. I pieced together my V3 kit over almost a year and I probably have that much into it. This is much easier, especially if you can beat him down a few hundred $$. I would go for it, but I would make sure you can get paperwork for the rebuild stuff just as peace of mind. If it visually looks good, and no weird noises or shaft play, you are good to go. Get your fueling right, bolt this on and go!
