It is a good dual-band ham radio but a little long in the tooth. One well-known issue they had was pixels would start to form on the "cool blue" display. Eventually the display became unuseable. Kenwood had a sort of recall on them which involved replacing the display. However, they would only do it if you were the original owner.
You should ask the guy he ever had any issues with the display and if so was it replaced. You should see the radio powered up to be sure.
Other than that it's a fine radio. Does cross-band repeat, has alpha tags and can be remote mounted.
