Harper,
I'm assuming you're not talking about me here, but It was very easy for me to see when I placed an 07 next to a 2011 where the quality was lacking, or rather than say lacking, was not the same. Saying it was lacking may not be fair because the quality is still better than most.
The interior materials for example seem to have been cut dramatically, and interior panel gaps specifically were no where near as tight. the carpet quality seems drastically reduced, etc - In all the 4runners I've owned, I have literally had ZERO servicable problems, not one that required dealer intervention that wasn't caused by myself - the 5th just happen to have required a replacement drivers seat, a replacement XM tuner, and replacement mirror as the LCD went out for the camera (I believe the last two were caused by the same incident, whatever that was because those 3 things all happened with in about 4 weeks)
Unlike most, I do nearly all my own work on all my cars with very few exceptions, I do my own oil changes (except on the GS430 where work pays for them), I rotate my own tires, I build my own 800hp monsters, I've had the head off more than one car in my garage, and at least 5 motors on motor stands that i can count off the top of my head.
I don't do this for a living, I'm an enthusiast, I've owned a ton of cars because it's what I like to do and what is fun for me, so again I'd say I came from a place of significant experience and knowledge prior to me making my decision to buy a 5th gen...
I appreciate a good conversation and even opposing views - what I don't appreciate is being called a Liar, or uneducated by someone who knows nothing about me, or what makes me tick... and guess what, there's more than one engineer on this forum - The difference is I don't need to convince anyone of it.
