I'm looking to purchase a used 2012 SR5 Loaded 4Runner with 36k from a non-Toyota dealer and they only offer to give me a after market warranty that I'm not hot on. Is there anything problems that 2012 4runners SR5 are known for? I wish it was at a Toyota dealership for a Toyota wrap gold warranty. With all the electronics and add-ons it's worth the $$ for extended warranty in my opinion.
