I know nothing about cars. I'm a 69 year old woman, love my 4Runner, hate to part with it, but the engine is toast (I think the last mechanic that installed new timing belt and water pump 1 month ago screwed it up). Does it make sense to spend thousands of dollars to install rebuilt/reman/used engine in a car with this many miles? My common sense says no. I have the funds to get a new used 4Runner but I prefer the 3rd gen d/t the smaller size and increased ground clearance (my permanent home is in the mountains of Colorado) so I'm also nervous about buying a car that old even with low miles. The only mechanic I know and trust is in Salinas. Any advice would be appreciated.
