I highly recomend the jeep owners bible by Moses Ludel it tells exactly what to look for on every era of jeep made made, and it is written so the average person can make sense of it even if you have very little mechanical knowledge, but it is not for idiots, it is also helpful if you are very mechanically inclined. it can be found at almost every book store I have been in. i own 2 of them he puts out a new one every few years, but the old information stays the same, he just adds the newer stuff also if you are looking for something that is compatable with many parts, and you can get parts for easily you want something 1976 and newer, I thought all the one's from the 70's wher compatable when I bought my 73, but it turns out only 76 and up are 72-75 are probably some of the best made, aside from the weak frame on the non renegade models, but real oddball years, not compatable with anything other than 72-75, and really hard to find parts for, most parts must be fabricated"
