Any advice before I buy a 99 Frontier?

I've got a friend of mine who has one in mint shape. He's buying something new, and is giving me first crack at it. Any common faults I should know about first?

Thanks in advace

There was a fuel pump Sending unit recall Out on those models .. other than that , as long as your buddy matained it you should be in good , shape. They are very good trucks.. Oh the only other thing that could be costly , is if he needs a timing belt but thats the worst of it..gl
