I've owned this for years, having purchased from original owner with 43,000. 23mpg in a 4WD is fine with me. Excellent balance for serious backwoods use. Highway power is low for passing, but fine for rock crawling and bogging or going skiing. This vehicle has been totally reliable and has never let me down in over 160,000 miles (total miles 233k) of some very tough use. No unusual expenses other than regular maintenance. Its not high performance, but a truly useful and practical vehicle. I don't believe any competing vehicle built in 1990 would hold up nearly as well, and it still looks good. I strongly recommend Bronco IIs.
I bought it brand new and drove it in some of the most torturous weather conditions...winter in Alaska, winter in Upstate New York, winter and summer in Utah, and then back to Alaska. Yes, including the Alaska/Canadian Highway in both directions. The water pumps are a problem but other than that I did virtually nothing to it until it had over 250K miles. Still own it but only as a toy and memorabilia now. Hasn't been driven regularly since 2004 but a couple of months ago, I squirted a little starter fluid in the intake and it fired up. Not bad at all considering it had not budged in at least a year at the time.
I've put over 20,000 miles on my B2 since I got it. I've done nothing to it. It just keeps going, and going, and going. It's the Energizer Bunny on wheels. I've heard of reliability problems with the tranny, but mines fine. It's just a bit noisy. The transfer case needed to be stronger as well. I love mine though.
This truck has been the best vehichle I have owned. It currently has 175,000 miles on it and runs like a top. I hgave never met anything I couldn't pull and all I have done to it is replace the clutch. The only other problem is the push button 4x4 does'nt always engage on the first try. I had a 1990 eddie bauer before and couldn't keep the transmisson in it but my current one is a 5-speed and has been great. I highly recomend this suv. Very reliable.
