On the car, I had a 2010 that I got in 2009 when they came out, and wouldn't likely do it again. It gave me trouble at 100k miles, I've mentioned here it needed a new transmission for one, and had some other engine things going on. But, that was an older year I owned, and before their redesign to a smaller size and maybe some corresponding adjustments. Aesthetically I like the Acadia over the Highlander, but I'd have some hesitation if I were to do it again and would see what's said on the 2018 models. Inside the cabin, I will say it was great and I miss it, and much quieter and more comfortable ride than what I drive now. It sounds like the miles are possibly high, maybe, sounding this out that's 2018, 2019, and then some unknown number of months driven before 2018 rolled in, and just two now for 2020. I'm thinking I'd want something under 25k miles if I could find it, for a 2018, dreaming, yes maybe, but it's quite possible. I think I'd keep looking if it were me, but then that's because I had one before, and also would right now like a Highlander or a Pilot (although I'm not getting either, just buyer's remorse on a van rather than three row SUV again).
Did you run a KBB estimate or Edmunds and see what it's saying for that year and model on miles, price, etc?
