I'm looking at a 2016 ford flex limited with low miles to replace one that I totaled hitting a deer. It has two minor accidents on the carfax report. I've already taken it for a test drive and inspected it and the only damage I could detect was a slight crimp in the rear crumple zone on the passenger's side, and the passengers side rear door being a bit off balaned, which the dealer has fixed. It drives like a dream, all the lights and electronics are working fine, drove 90 on the freeway with zero pull to either side. Just wondering what, if anything, I should be watching for. No codes, no check engine light, no whine, wobble, rubbing etc. The collision sensor was wonky, but they claim its good to go now, too.

Any advice appreciated. Thank you.
