I have had every generation of Tacoma. I think each generation has gotten better but the 1st gen was a better truck for builders.
I will give you the good and the bad of the 2018 I have.
The good, it's zippy and fun to drive, I have the off-road with the locker, crawl control and terrain select which add more off-road. capability than most people can ever use.
Toyota Safety sense with the adaptive cruise control- I am a big fan. It has some quirks you will have to learn through driving experience (vehicles turning right on the right shoulder will cause an emergency braking event. Not to scary tap the brake and drive on. You will learn the triggers. I like the auto high beams as well. Like the cruise control and auto braking it takes some getting used to to trust it.
The gas mileage is both good and bad. This truck responds to speed by eating more gas. If you are plodding around in two lane roads with no stops and 35-60 mph you can expect to beat the rated highway mpg for those type of trips. I have logged many 25-27 mpg legs like this.
If you get on the interstate and cruise 80mph you can expect 15.5-17.5 mpg depending on wind.
I average 19.5 mpg per tank with a combination of city, high speed highway and the easy slower cruising described.
Power band- it's good and bad. It may seem sluggish but you cannot he throttle shy with it. Push it and it rewards you as it opens up. Personally I think it's fine. I can lug around in Atkinson mode for a while and open it up to get on an on-ramp and the engine literally changes personality. It's not a a lot of power but compared to the 4 runner. It's "zippy"
Interior and comfort..separate those terms if you are near 6' or over. I can stand it at 6' but I take a break every hour or. Two. The seat does not have enough cushion length for my liking, I have big legs from a life of sports and powerlifting so it's noticeable to me,. Bolstering and material is good and many people do t have any complaints.
It's easily serviceable and has a large support network online
