What are you looking fer in yer search fer a T-100? Manual or auto? 2WD or 4WD? Camper top? DX or SR5? Power windows/locks? I personally would stay away from the 93/94 years with the 3.0 engine even though I have a 1993 2WD SR5. Stick to the 1995 to 1999 ones...with the 3.4 engine. I believe that starting in 1997 the front seats were buckets. Usually if you see one with chrome backed mirrors, they are power mirrors.
There's a couple in craigslist fer Montana...
