You want 5K? Answer these questions:
1: Whens the last time the timing belt was replaced?

2: Spark plugs?

3: Plug wires?

4: Distributor Cap?

5: Distributor Rotor?

6: Head gaskets? Front & Rear??

7: Whens the last time the transmission fluid was replaced? And what type of transmission fluid was used? I
would hope/expect to see documentation on this as well.

8: Whens the last time the rotors for the brakes were replaced? Just cause your "Pads" are good and have plenty of life left, doesn't mean shit if the rotors are warped.

9: What kind of fuel have you been using over the course of you owning the vehicle? And YES - this MAKES A DIFFERENCE as to your asking price.

10: Whens the last time the tires were rotated & balanced?

11: Whens the last time the alignment was checked?

12: Whens the last time the radiator was flushed & changed?

13: Whens the last time the brake system was bled & redone?

14: whens the last time the thermostat has been replaced?

15: whens the last time the waterpump was replaced?

16: Whens the last time the syncros were repaired/maintained last?

I'd prefer to see all the documentation regarding this vehicle, as you're asking for 5k, I'd like to know why, and what exactly has been done, completed.
