Classic Jeep CJs. Between the varying members of my family, we've owned everything from CJ2As through CJ5s and Jeepster Commandos. The numbers of good used examples are less every day, but there are still enough good ones out there that you can afford to be choosy. Some things to look out for when buying a used Jeep CJ:

• Rust on the frame near the rear spring shackle. They all have it, but avoid ones that are rusted through.

• On the body, rust around the door, and rust in the lower front fenders. Fenders are easy, spend a couple hundred and replace with fiberglass, the doors take a little more work.

• Diamond plate aluminum, while cool looking, is often used to cover up rust repair. Be wary of it.
• Windshield frames tend to rot on newer CJ models. This is usually easily visible from the outside of the jeep.
• Plastic valve covers on '80's CJ 6 cyl models have a tendency to leak. Replace with an aftermarket aluminum one.
• All 6 cyl inline engines leak some oil. Just find one that leaks less than the other ones, and you're doing pretty good.
• Look out for bad lift kits. Spring-over-axle conversions make a good lift, but are rarely performed correctly.

• Check all fluids (including axle gear lube) for water. People who own jeeps tend to find mud and water relatively often (go figure).

Anyway, a fair price depends on what you're willing to spend. Expect to find good running examples for less than $1500, and beautiful parade quality examples for around 5k. Never pay over $10k for a classic CJ unless it is a museum piece, and you are buying it for your own museum.

Hope this helps! If it does, please indicate so below. Thanks!
