Thank you for letting me join. I have ordered a 2019 Limited that will be replacing my 12 year old 2006 4Runner. I look forward to learning more about the Sequoia, and I understand that there will be very few differences between the 2018 and 2019 models. First question: I was told the Flex-fuel engine option was unavailable. Does anyone really use Flex fuel anyway? Are there any performance differences between the two engines? Thanks!
