There are +s and -s to buying a gen5. I traded in my 06 with 150k 2 months ago after a week rental of a SR5. The first plus is look the 2014-7 aggressive look, just awesome (IMO), ride is not as harsh (fewer complaints from Mrs), engine is stronger and I can go on and on regarding the pluses.
The negatives are some of the deletes, 1. The climate control was really nice, set the temp and go, 2. getting rid of the soft close rear hatch, 3. flick start and 4. hydraulic steering in favor of EPS 5. Glove box design in the gen4 everything stayed in place and the hootch door and last loan payments.
All this I love my said I love my 2016 Trail MGM and would not trade it for anything else.
