My 1999 Ford Explorer wot go into reverse?

Hi the modern car has a life expectancy of just 8 years or 100k miles. Beyond which it becomes a money pit. This is the modern fact of life. So time to thinking more in terms of replacing the whole car. Not just the engine it also has an engine management system the computer which controls how the engine works. So it is not just case of changing this or that.
