Based on the minimal description I'd pay $2500 if its a 5speed no problem.
After more pics and seeing the car in person, I can see how it may be worth even more.
Above $4k I think is a bit much, unless there are some really nice recent parts on the car and you can guarantee a clean safety. IMO
Lets see a few more pics! Get a little auction going here. Who's got $2600??
