I'm looking to buy a 2001 or 2002 Toyota 4Runner. Do anyone know why the AutoOninfo.net's reliability rating is a little higher in 2001 than in 2002? I know this is only a slight variation, but wondered if there was a known reason. Also, what is generally the more preferred model? The Limited, or the Sport Edition? The Sport Edition does not seem to come with leather, but I love the raised air vent in the middle of the hood. What other differences are there between the two? Do they have the exact same engine? Thanks very much in advance!
