Thank for the info on your 2016 Edge PTU. It is encouraging that the fluid looked at 28K.
My question re the 3.5 vs the twin scroll is related to long term reliability. The 3.5 has a good track record but can't find much about the reliability of the twin scroll 4 turbo. We have the 3.5 in 2009 Mercury Sable that my wife still loves.
It would be great to get a little better gas mileage from the 4 but i am weighing long term reliability fairly heavily.
If I go with the Edge I will likely keep it quite a while. The vehicle it will replace is a 2003 Buick Rendezvous that only has 103,000 miles on it.
For now I typically use rental cars for anything related to business that involves over 200 miles or so round trip. I had a 2015 Edge rental last year and really liked it. It was a 3.5.
Thanks again for the info.
