He complained about your car? Ummm... least you have one! The ungrateful @ss should never be allowed to use it again.
My response to when a guy complains about something of mine (that of course they're getting good use of- like my tv being too small, etc), my response is simply: "buy me a new one"
I work hard to pay for everything I have, and am supporting myself. If something of mine isn't good enough for you, either deal with it and hold your tongue, or shell out the $$$ to buy me a new one

This usually shuts them up quick cause they're as broke as i am!
