I have to admit, I've never owned a 4-runner, but my 76' blazer had a roll down rear window, and to be honest I never really missed it much. I don't really understand why 4-runner people are so attached to that feature. I do understand it's handy in a garage etc. if you can't raise the lift gate. Perhaps it's because I've never had a vehicle with a full lift gate, my S10 was split with a tailgate and I never found that too annoying, except that every 2-3 years you had to replace the lift shocks.

Now what I would miss is no tailgate, I much preferred having a split liftgate/tailgate on my S10 blazer, pickup, and 76' blazer that you could drop and sit on, work on etc. without having to make room in the cargo area. I suppose the slider could work for that, but only if you have nothing in the cargo area. It's all relative though, it's also a lot nicer to not have to deal with a tailgate in the way trying to get cargo in/out. I suppose whatever we've had as a feature is easier for us to become attached to.

But lots of people get attached to a feature, when GM came out with the new pickups that didn't have a column shifter, oh my goodness guys were more upset than a baby no one had changed a diaper on for days, swearing up and down they'd never buy another GM pickup.
