I don't need a 4th vehicle but situation has presented itself that my little brother is selling his 2011 focus 55k miles for $6800. A dealer offered him that in cash and he's doing it today if I don't buy it first. It does need a major detailing as he has messy kids, plenty of dings, and the AC has went out (mechanic said $70 egr valve). I would need to sell one of my vehicles eventually but it seems like a smoking deal. Would I be crazy to pass it up?
