My 92 Cherokee 4.0 I6 has 180k on the clock, a bad connecting rod, and a shotty transfer case and it still gets me to work and back every day. All city miles. I bought it from a friends parents for $500. That was before it started falling apart though.
When I finally shoot the rod through the block I think I'm going to replace the engine. I love the thing too much to get rid of it. Its the most trusty beater Ive ever had.
