I have an '06 Tacoma 4x4 with the V6 SRS package.

Mostly likes so far, but a few dislikes. Interior plastic trim could be a lot better and there have been quite a few recalls for assorted problem areas. All done promptly and with a minimum of fuss by the dealer. YMMV there, dealers are dealers...

I get around 18 mpg with mine, however I'm not an aggressive driver. I'm the guy in the right hand lane going 1 mph over the speed limit with the cruise control on smile

Ride is a little bouncy, to be expected from a 4x4. Not nearly as bad as my last 4x4, a Dodge Dakota.

Plenty of interior room for bigger guys, (I'm 6-1, 230) and comfortable seats.

No regrets here, I'm satisfied with my purchase. Most of these guys are, too:
