My first post here. Happy to find a place to get good information. I'm shopping for a GX470 and found one that I liked and test drove it. It's a 2008 with 200k. The car felt solid and had good power on the test drive. It had a little more rust than I would have liked on the frame. That said, it looked like it was more surface rust that actual destructive rust. The body was very good, with very few imperfections. The thing that spooked me was a smell of burnt antifreeze in the engine compartment. I think it was more from the passenger side, but not sure on that. Could this mean an expensive fix, like maybe a water pump, or leaking heater core? The seller said the timing belt was done recently, but I think he owned the car for a short time and couldn't be specific on when it was done. Any information would be helpful!
