I came from a 2018 limited to a 2021 limited nightshade.
Not everyone is in to the limiteds. Many of the changes i like for 2021 arent exclusive to the limited, but all the same, it’s worth pointing out that’s where my experience has been. the 2021 model is my preference. the adaptive cruise control, CarPlay, LED headlights, larger screen multimedia, better sounding stereo system (the 2018 JBL system was great, but this is even better), remote start (and other connected services) and blacked-out interior sure do make it feel a whole lot more modern. Quite a few significant, small touches make for a much-improved experience for me. I love the balance of retro and rugged with the 4runner. After 3 years with the 2018, I can tell you the upgraded tech additions sure do help round it out for me. Yes, you can get an upgraded head unit with CarPlay, but I am unimpressed with the final look of a replaced HU and console mods to accommodate it all.
Most of my time behind the wheel is spent driving between Utah and Wisconsin. I dont do a lot of 4-wheeling but I do spend a lot of time on dirt roads. Couldn’t be happier with my 20201 nightshade LE. I hope youre as happy with yours regardless of what you choose!
