Some answers for u
1 - This pickup is the reson for the old famous lingo "drives like a subaru" - no problems with it, drives no matter what, cheap parts and maintenance. 2 - The last model is 1994. It is usually cheap to buy, so get the latest model u can afford. I am not sure about problems in older models. 3 - 4X4 are ridiculously over priced, if u will find one. I say - stick with the 2X4. I don't use it off road, not more than any other private that is. If u have any other questions - send me a message.
