where can i find the best deal on a vehicle, ie.criagslist,auctions,private,repo’s,gov’t, or anywhere els

i am looking to get a real steal. i know cars very well and can fix most things, except maybe rebuilding an engine. with a combination of my mechanical aptitude and a place to buy a good deal, i would think i would be able to swing a real bargain somehow. i am mostly looking for a 1986 to 1995 jeep cherokee, unless i find an amazing deal on something else. i just don’t know where the best place to get my deal from, do you?
