There is a really good 3FE mailing list on Yahoo Groups that you'll want to join, [email protected]
Good news: there is a lot of good aftermarket stuff for 60-series Cruisers, and they are easy to work on. Parts still readily available from Toyota, and there is a great network of owners (for example on aforementioned list) with parts to trade and etc. Good trail rig; lots of torque, heavy duty.
bad news: they are heavy and slow on the freeway, take a long time to stop, get bad mileage. As in any other older Cruiser, body rust can be a problem depending on where it has spent its life so far. 3FE engine has a few known issues which for the most part are easily remedied.
