HELP I need a reliable used car

Was just talking to one of my patients. I mentioned looking for a reliable used car. They have a 1993 Toyota Camry wagon that they bought brand new. They stopped using it because their dad got too old. They said $500 and I could have it. Looks like all the ratings on those are great. I’m going to take it to the local shop I use and have them run all the tests on it.
