My friend had a 1st generation Edge. She loved it despite numerous issues with the A/C, multiple check engine lights, and a few ignition coil replacements. She recently traded it for a new Subaru Crosstrek and still misses her Edge. She wanted a brand new Edge, but the prices were too high for her to consider.
I have recently thought about a new 2020 Edge SEL AWD myself, but that is only because the 3.5L V6 is gone and replaced with a much easier to maintain 2.0L EcoBoost 4cyl. The poor headlight performance. despite having LED headlights standard, is kind of a deal breaker. Plus, the rumor that Ford is killing the Edge in 2023. I keep a car 5-6 years and don't want to knowingly get in to a vehicle that will be discontinued for 1/2 the time I would end up owning it. Not to mention the effect that would have on the already high depreciation of Edges. Tons of discounts on the Edge right now, though, so that might offset depreciation later down the road.
There is always some sort of gamble with new vehicles. As JayTee said, try to do as much research as possible. Visit the owners forums, read reviews, long term tests, YouTube reviews, etc. Sure, it might result in some "paralysis by analysis", but if you can identify recurring themes it can help fine tune your expectations.
