Physically look at at least 5 more 2002's -preferably in his price range- constrast the results with this one.
Have a final plan of what you want this car to be. Then create a budget on what it will take to get the car to that point. More times than not a better condition example for more money is the best deal. Paint & body, interiors, trim, motor replacements, and parts aren't cheap anymore as they were before. Even trashed parts cars are going for a lot of money today.
