2003 Toyota Tacoma 2dr Xtracab Rwd SB (2.4L 4cyl 5M)
2.4L automatic, extended cab 2WD SR5. So far, I'm getting 25 mpg. The smallest engine available, but has perfectly adequate power. This is the first year for standard ABS, which was a hard to find option. I searched forever for these features in a used truck, really glad I found it. I hear the '05 and newer Tacomas don't have as good build quality, they're larger and don't offer the 2.4L. If you're looking for great reliability and mileage, I'd get an '03 or '04.
Extended cab. No extra interior room without it, but you still get a 6 foot bed with it, unlike the 4 door. Nobody will ever ride back there, but it's good inside space to put a few groceries, etc.
Hard to find luxury options on Tacomas. Sun roof, Power locks & mirrors, and power heated leather bucket seats with lumbar adjustment as found in my '99 Avalon would be great.
