I have a 1993 Ford Explorer Eddie Bauer with 153,000 miles on it. Recently, the head gaskets have blown. I have already replaced the transmission about 7,000 miles ago and the radiator. I know the radiator and transmission are major fixes. If I go ahead and get the head gaskets fixed (I found someone to do it for $400), do you think anything else (major) can possibly go wrong? If so, what? My concern is that if I sell this car and buy another used SUV (under $5,000), the new SUV may have some of the same issues I have had with my ford. And I can't afford to buy any fairly new (2005 and up) SUV right now. Any suggestions?
