There are a crap load of questions that can go to how much you should pay for the car. Your already going to come out of pocket to fix a water pump and the head gaskets.Past this is it driveable right now so you can test drive this car(If you can't test drive it, I say you leave it and don't buy it all because there could be other stuff wrong with it)? If so, have you test drove this car(you should, and if you don't know much about cars bring a mechanic or someone that does know about cars with you)? If you did test drive it Did it run smoothly when you did? If it's a stick shift are the gears grinding when you shift into another gear or take off? How does the clutch feel on it, does it squeel or is it rough trying to press in(you don't want to have to replace the clutch that stuff sucks, combined with the replacing of the water pump and head gaskets? Is the break's grinding when you press the breaks or stop? These are just a few things you need to look at, you don't want to have to buy new CV Joints, break pads, and all of that other stuff.Past that Justice brought up a great point, it's really about the mileage on the car sometimes, more than the years on it. Checking the mileage on the car, along with how regularly the oil was changed along with the mileage can be great to know. If it's more than 250,000 miles, I would leave it. If they went longer than 5,000 miles without getting the oil changed leave it. I know 1,000 dollars seems cheap, but if it's breaking down, that car can easily run you up to 3,000-4,000 dollars to fix it. So look into all of that before buying this car.
