Why are used Toyotas and Hondas so expensive exag

I know they are reliable and have simple and basic engines that last longer with minimal maintenance ( I know average car owners only do oil change ), but come on I see 2005 or 6 models with 300k miles for sale asking for $3000 or more and they say because “it is a Toyota” I mean can people not buy them for those prices or not offer more than they deserve ? People sell for that much because people buy How did used cars market become like that
