I have sold my 94 Toyota pickup on the search for something bigger and faster. I have found used 2005 GX with 130k for sale at the local Lexus dealer. The service records are as good as you can ask for, it has always been serviced at a Lexus dealer including the 90K service. But right after the dealer put it for sale the radiator was replaced is that something to be concerned about? Possible over heating issues? i have owned a lot of high mile Toyota's and have never had to replace the radiator. Besides that there is some minor surface rust on the frame welds. Everything else is in great condition!
