I have a soft spot in my heart for the 1st gen. I've owned three of them. Gutless wonders but that was always part of the charm.
I am very much enamored with my 5th gen. It has everything I want as a consumer. If it had a manual tranny, you would have to pry it out of my kids, kids, kids, cold dead hands. For me this would be the holy grail.
Honestly, I do like all gens. I've been a Toyota truck fan since I owned my blue Stompers Toyota 4x4 back in 1984. I didn't have a poster of a Lambo on my wall, I had pictures of Toyota trucks and 4Runners, true story.
