Really considering buying a Jeep. I'm looking at a 2004 w/ both tops, 6 cyl, auto, 2017 wheels and tires with 2,000 miles....and 45,000 miles on the Jeep itself. It's spotless, but really is more money than I want to spend just to play around. It has a plow that's rarely been used...I can sell that and get some $$$ back. I was ready to pull the trigger....just because I think it will hold it's value and it doesn't need anything right now to be an awfully nice toy. Here's the problem.....I came across a 97 today. Obviously not perfect....but very, very little rust, just the soft top which is fine, good wheels/tires & decent interior and I can probably get it for $2500 or so. Issue is it's a 4 cyl. It's a manual. How much headache is it to swap in a 6 cyl....or maybe even something else.....Chevy V6 or a small V8? Neighbor is a mechanic with a building/lift/etc and is offering to do the work/help in exchange for some cash and beer lol.
