I've found 80's Toyota trucks not only hold thier value but appear to become more valuable as time goes by.
I saw the 82 long bed I used to drive back in high school(1989) over thanksgiving weekend. Asking price was $2,000 with almost 200,000 more miles on it that when I owned it.

Current truck is and 88 V6 4runner I bought for 3K, worth more now even without all the ARB/OME stuff.
