... you want.

there are Lanolin-based rustproofing sprays, in spray cans. But you need protective clothing, respirator protection if going the DIY route.

can be fixed

that said, i wonder if any jeep driver has a death wish.

It had the death wobble in spite of a bunch of suspension steering repairs. Went away with a steering damper installation.

drove a black Jeep Wrangler (probably late 1990s) which he outfitted with a mobile data terminal and police radio. i thought it looked fantastic and the reason I mention is occupation is he was confident enough in its performance to use it for undercover work and law enforcement related travel. In my unprofessional opinion that shows a high level of confidence. He drove that thing into the ground. Now that I no longer have a dog I guess in theory I could get a Jeep now. Great though that Jeep was, it was not very big--not big enough to carry much stuff. There are probably big Jeeps and small Jeeps though.

Sorry, not a fan. Get a Toyota.
Or at least be prepared mentally and financially to be constantly fixing/replacing stuff (buy a second/third for parts)

Three things I would highly recommend.
1. Take your time, there are tons of them.
2. Make sure the engine compartment is clean, no oil deposits etc...
3. Take it to a mechanic, and get firm answers.
No leaks, skid plate is a must if you do any off roading, any wiggles or shimmies, run and if it's from a dealer, get a Carfax, no exceptions. if they won't give you one, run lol.

Oh and lastly, if you can drive a stick/manual, do it because it's funner, better for off road and funner lol.

Both were rust buckets. Took the body off the cj5 and put a fiberglass body on it. Raised it 3", put bigger wheels, nerf bars and painted it red. New top and it was sharp. It had a small v8 in it. I gave that jeep to my son and he drove it through high-school and 4 years of college. The cj7 had a six cylinder and a hardtop. I used it mostly around the homestead.

Even though I had two of them, I don't recommend them. Once they start rusting, it's just a matter of time they look like shit. The mileage was terrible. It didn't matter between a v8 or six, 12 mpg is the average.

Definitely get it checked out (I'd say that about any car) by a good mechanic. Find your local Jeep community, get some ducks and enjoy!
