I currently daily drive an 11 with no problems. When I daily thrashed my 97 I had to replace my power steering pump twice and had to rebuild the transmission. Both of those problems were my fault. The heater was weak and the top sucked so it was cold. I drove my 92 and 89 with nothing more than maintenance for years. I've never had a fender rust, transfer case detonate, windows cut(I threw a snowball through the back window of the TJ), or rolled any of them. The current jeep gets around 20mpg, I have no clue about the others. I haven't lost money or been stranded by any of them.
