I have owned my 2002 IS300 since 2004. I'm just not using it, and it is sitting on the drive, deteriorating. I am very attached to it, and haven't sold it because I don't want to to go to some 19yo to rag it, or to be cut up for spares. The engine and gearbox are still fantastically smooth. There is a very small amount of body corrosion.
It's probably worth about £500, but if I sold it, I would want it to go to someone who had the time to sort the body work issues (I have been quoted £800), and drive it gently.
What would you do?
