Your major concern is going to be the back end of the car, from the
rear bumper support, to the gas tank. They rust, and badly back there.
If rusted bad enough, the gas tank falls out. My son got a 2002
V6 with about 115,000 for $2700, and the rust is manageable because
it was garage kept. I was going to buy it, but I needed a few more
MPG, and it was just too low, so he bought it. Plus, a 3.8 only getting
190 HP, when my former 3.5 V6 Charger was doing 250HP, nope...
Shortly after, the thermostat stuck closed. The owner had been getting
a check engine light, and claimed there was no code stored, well he
was a liar. It was for a cylinder head over temp, and as I said, shortly
after the thermostat failed. Luckily, there was no discernible damage to
the motor after replacing it. IT had over heated three times, and we
talked to the guy who sold it to us, he decided to have a hissy fit, and
said he'll just take it back. Well, my son wanted to keep it. This dude
is a cop too, and even when not on duty, don't know how to talk to
people.
He has had no problems with it otherwise.
