My .02

By the time you bring the new vehicle home the tech will change or most likely be outdated. The selling point on my previous vehicles was tech and I bought it hook, line and sinker. 17 months later I realized what a waste it all was and here we are today. As another poster mentioned there isnt much the car can do that will be better than a cell phone. Blind spot monitoring or parking sensors are nice, I do miss that, but not a the cost of losing comfort or flexibility in the vehicle or how you use it.

I guess in the end you need to decide what exactly you are after.

I do not understand why the op needs to replace his 2014 with a new 4runner.
I have a 2014 and plan to run it another 9-10 years like my last 4runner.

If you want to upgrade some aspect of tech, you could always get a new headunit with apple car play. One of the perks of the 4Runner is the simplicity of it allows for easier customization.

One thing to consider:

Toyota issued a FULL halt on aftermarket accessories, both 3rd party and OEM, on anything 2018 (might be 2017 too) in the Toyota trucks line up (Anything with safety sense). The "tech" you are hoping to get comes with a price. The safety sense technology has lit up the christmas tree in the cluster and placed vehicle in limp mode due to modifications to suspension, braking and a myriad of other tweaks we all like to do. I found this out at the dealer the other day when I was inquiring about the 2018 Tundra we are going to add to our family.... I cannot remember if they states it was on the Tacoma as well, but he did say all trucks and anything with safety sense... May not be relevant to the Tacoma you are looking for though.

I also came over from a ‘16 taco turd. Go check out Tacomaworld and read about the dissatisfaction of the auto, rear diff howl, cam position issues, etc, etc.... If you go that route take it for the weekend and buy a manual. Make sure you love it, but my bet is if you get one you’ll be back here in a year with a lighter wallet.
