Dude 4000$ is a down payment on a new car. Paying 4k for a used 170k mile car is not worth it. No matter what he says you can count on problems within the next 25k miles. With the econemy you can probably get a newer GP for a very low price.

I Put 5k down on my car, paid a total of $17k for it with 8k miles. 200$ payments a month and paid off in 1.5 years.
