The only code I find myself having to rewrite is something that is both (a) broken and (b) undocumented. If it's documented, with lots of comments letting me know what the original coder was thinking, I have a fighting chance of fixing the problem. If it's not broken, I'm not fixing it. I've got way too much other code to write to worry whether or not something is elegant or pretty.
