That's too much for a collision salvage, especially when the seats are ripped up. Like Mkazm83 said, that's kind of shady. Also, 120k is decent but that age is getting into replacing several things like the cv boots or axles after ~20k miles, maybe water pump in the same range, also all hydraulic cylinders (brake and clutch) even sooner. The timing of these things is predictable, I've found. And they are VERY expensive.

In Fresno you can probably find a clean VTEC for $5+ or a clean Si for what this dude is asking.
