What can be said other than you fall into the oddball category that can't accept change. Most thought the gen2 was a vast improvement in the tacoma styling, the gen3 had even more aggressive good looks. As for the gen4, I have some agreement that I think toyota went a bit too far with its exterior styling, but if this has positive effects on fuel economy, and wind noise, I'll accept it for what it looks like. I wouldn't derate the gen4 till you've taken a test drive in one. Imo, it performs better than it looks. For someone that has a tired worn out tacoma, and wants to stay with toyota to begin a new chapter, I think the gen4 will be still a good choice, although you might not like the initial cost, or the maintenance down the road, but this is where the entire auto industry has been pushed to go.
Just read whats happened to Nissan. A buddy of mine recently bought a frontier a couple years ago, and is crapping his pants his frontier may become worth zilch.
