I have the base model with the 4x4 5 spd. The window sticker is something to behold. Mine has no ABS, no chrome package (I've rectified that), it did come with alloy wheels, cruise control, 4wd, and a roof rack.
The base model never had option for a sunroof. Its the only trim that didn't get ABS standard. Other downgrades is it usually has only 4 speakers instead of 6.
A truly speced down one wont have a lot of basic nice things like heated mirrors, sunglass holders, or keyless entry.
The 4 cylinder engine is a great engine, debatably more reliable than the 5vz. The only 2 things I've had to do (which are common) is replace a cracked exhaust manifold, and adjust my valves. The advantage is that the engine has a timing chain (and so its also an interference engine) that can easily go 200k or more.
You should really do a compression test if there is no record of adjustments being done, burnt valve can occur if the owner fails to adjust the valves, and you essentially have to redo the valves.
The engine is a breeze to work on or around, tons of space to work (especially without abs). The engine revs at 3000 rpm (redline 5500) on the highway, so its not the most pleasant thing to drive on the highway. It also gets disappointingly low MPG, I get 17-18 city and 20-22 mpg highway. And I'm stock so it only goes down from there.
Oh, and the 2wd is even more easy to work on since you don't have the 4wd components in the way if you need to redo the oil pan gasket
