IMHO CJ's and YJ Jeeps make uncomfortable daily drivers; the newer the Jeep, the better highway manners. However, good lift kits and other suspension modifications (read more dollars) can rectify the rig's ride quality. Jeep CJ's and Wranglers are poor choices for a daily driver also because of poor gas mileage. Of course, if your looking to buy an older rig that someone else built, it's going to cost much more (we won't even discuss the possibilities that you may, more than likely, purchase someone elses incomplete or poorly built moneypit). Lift kits, lockers, regearing, and other modifications cost the Jeep seller a great deal of money, and/or money and time. It's not uncommon to spend SEVERAL tens-of-thousands-of-dollars to build a respectable rockcrawler. Obviously, the Jeep seller is attempting to recoup some of the money invested in the built Jeep. However, if you should find a built Jeep in great condition, have it checked out by a very knowledgeable four wheeler who is a certified mechanic. If it truly is a good buy, buy it. But, it's unlikely you'll pick it up for under $5000.
Personally, I would never purchase another four wheeler's Jeep. My recommendation to you, where money is apparently a limiting factor, is to buy a stock used Jeep (unmodified). YJ's, and if you can find one, an early TJ can be purchased for under $5000. Keep in mind that 1996 - 1998 TJ's are now over 10 years old. I, in all good conscience, could never recommend any old school Jeep, older than 1991. It was basically in 1991 Chrysler packaged it's YJ with the 4.0 L 6-cylinder engine with electronic fuel injection ... it makes a difference, especially if you enjoy four wheeling more than wrenching on the trail!
In regard to wheelbase, CJ7's and YJ's had almost the same wheelbase, 93.5 and 93.4 inches, respectfully. It was the CJ6 and CJ8 (scrambler) that had the longer Cherokee-like wheelbase, 101 and 103 inches; the Jeepster was something like 104 inches. If you find one of these rigs, buy it and restore it, please!
The 4.0 liter engine is an 180 BHP powerhouse providing a lot of torque at low rpms for trail use. Old iron is old iron (read continuous repair). An early TJ is the vehicle you really should be looking for for a daily driver, IMHO.
Whatever Jeep you find and subsequently purchase, it will be difficult to keep yourself from spending money recklessly on this rig. At least, that's what others might say about your new passion. However, here on Jeep.wire, we understand this overpowering emotion and enthusiasm. Just keep writing, we'll attempt to walk you through the basics and help you avoid your family and friends arranging an intervention and possible therapy with your local psychiatrist. <img src="/forums/images/graemlins/lol.gif" alt="" />
